Can Step Siblings Date? (9 Noteworthy Tips)

Last updated on June 19, 2022 by Sonya Schwartz

Step-siblings being together is one of the controversial topics and is yet to be concluded.

While some individuals think it’s wrong, others have many reasons to say it’s right, and they act accordingly. This has probably crossed most people’s minds, especially if there’s a special connection involved that they don’t share with others. 

The thought of being with a sibling they really love or admire has crossed more minds than we care to point out. However, it’s a topic many people frown at, especially when they hear the word “sibling” in the sentence. Some sources will tell you that though steps may not be related by blood, it could feel weird seeing them date, especially when you know that they are family by law. 

Maybe it’s psychological; perhaps it’s not. But what matters the most are your personal choices and what makes you happy. Because as an adult, you know what direction to take to improve your life. So can you date them? Here are some things to consider.

9 Things To Consider Before Dating A Step Sibling

1. How did you find him?

How did you find him

First off, finding someone and falling in love with him is uncontrollable so dating your step-sister or brother is not as huge a taboo as it’s been made to sound. It depends on when and how you find him. 

Let’s say you are on a much-needed vacation where you meet a hot guy, and you’re both so attracted to each other before you know what’s happening. In this scenario, you met him without knowing that your parents got married, and it does not affect anything. As far as you both bond and are in love with each other. In that case, I would say that it’s fine.

2. Do you share genes?

When it comes to siblings being together, biological or genetic issues could be crazy. But thankfully, they don’t occur when it has to do with steps. 

So when it comes to anything that has to do with genes, there’s no problem at all. This is one of the possible things to be happy for, and it’s because you’re both not related by blood, which makes everything easier. So really, it’s not such big a deal as we imagine.

3. Is it what you want?

I’m guessing by now; everyone knows that every action comes with responsibilities and consequences. There are the consequences we’re OK with, and the rest tend to make us a bit uncomfortable. Make sure you are ready to meet during family gatherings or occasions that involve family members, friends, and your parents. 

Can you withstand their criticism and prying questions? If you’re sure you can, then go for it. But trust me, you won’t only feel judged, you will feel uncomfortable being around judgemental people even though your 'taboo' significant other is by your side. But if it means nothing to you, then you’re good to go. 

4. How long have you been together?

There are different case scenarios here that will determine if you can or can’t date them comfortably. The age or time at which you met can affect your choice and can help give you some direction on what exactly to do. 

Assuming you’ve lived with them for a long time, let's say, your parents got married when you were 5 years old, you’re practically a blood relative, and my advice to you is to look for romantic love elsewhere. 

But if you met when you turned 25, you’re adults that grew up in different homes and did not know each other so well; it's a safe bet. In that scenario, you can weigh a few factors and get into it.

5. Is it for fun?

Is it for fun

While some people may take relationships seriously, others just want to have fun and move to the next stage of their lives without stressing. It has happened, and it will keep happening. If that’s the case, then it’s probably not a good idea to date someone who is a permanent fixture in your life regardless. 

Remember, if anything goes wrong, it will be more awkward because he is your step-brother. 

So take some time to ponder on whether it’s really what you want or not. Let’s say you date and break up after a while; you’ll meet whenever you have family gatherings or vacations. I'm just going to take a swing in the dark to say you probably don't want to know how that feels, except you have very thick skin.

6. Is it against the law?

This is one of the first things you'll have to consider, and if you don't, others will consider it for you. Nevertheless, unlike incest or other unlawful acts, romantic relationships between steps is legal according to Family Law.

So, there’s nothing to worry about. You won’t have any jail time for it if you’re considering dating your step-sibling. Some religions could tag it as a taboo, but from a societal standpoint, it’s nothing wrong. So, don’t feel bad about going into it if you’re sure it’s what you want. But if the feeling is not mutual, or he’s underage, then I’m afraid that could land you on the wrong side of the law.

7. What are your parents’ thoughts?

Yeah, this is where we get to talk about your parents a little bit. It may be mostly your decision, but you also need to think about how they’ll take it when you finally spill the proverbial beans. 

This whole situation entails that your parents are already together. Now ask them how they feel about you two dating. They could disagree initially and accept it later on or vice versa. 

But whatever the case may be, give them more time to assimilate it. You may probably have many talks, arguments, and disagreements about or it could simply be smooth. But, let them know because it affects them too.

8. Can you openly accept him?

What makes a situation look good or bad is how we accept and present it all together. When we’re shy about things we've done, it’s easy to ride on that, but when we present them with pride, it’s accepted for what it is.

When you keep hiding or making it look like what you’re doing is wrong, it’s easy for society to feed on that. They’ll give you more reasons to think what you’re doing is not acceptable. If you know you can date and accept him publicly, you’re good to go; if not, then you should reconsider.

9. How does he treat you?

The list could go on, but it'll be incomplete if we forget to put his attitude on the scales. All the points listed won’t matter if he doesn’t treat you right.

Is it like pulling teeth getting him to spend time with you?
The key to solving is understanding men on a much deeper emotional level. The number #1 factor that causes men to behave this way is actually relatively easy to change with a few subtle things you can say to him.

Take this quick quiz to see if he actually likes you!

Dating your step sister or brother is like dating any other person out there, and it’s good to be convinced that he will have your best interest at heart. If you feel you don’t get as much attention from him as you should, or he’s simply nonchalant when it comes to your feelings, you may want to rethink the whole situation. 


Is it weird for step siblings to get married?

Well, not everyone has the same perspective when it comes to situations like this. Some people are not so comfortable with it, especially when they know your parents are together. Initially, it could be weird, but later on, everyone gets used to it.

Is it illegal to marry a half-sibling?

There’s no 'yes or no' answer to this question. For the most part, it depends on where you reside and the laws governing the region. I have heard of so many countries that don’t accept it; that's more common. So make your findings of the laws governing your country of residence to be sure.

Can I date my half-brother?

Dating doesn't have any rules or laws guiding it anywhere. You’re free to date anybody you want to date as far as you don’t plan to get married to him. Societal laws don’t permit half-siblings to get married. But you can date him temporarily if you really want to.

Do half-siblings count as immediate family?

Every sibling counts, whether they’re blood-related or not. Half-siblings are closer than steps because while steps can get married, they can’t. You see, they share a parent, hence the fact that they are blood relatives. As blood relatives, they equally count as immediate family. 

Why is incest morally wrong?

Apart from the fact that it’s illegal and genetically wrong, many cultures do not accept it. Incest brings damages physically, mentally, psychologically, and otherwise to the parties involved, their kids if they have any.

The Bottom Line

Step-sisters and brothers dating will always bring a weird aura and foster unanswered questions from all angles. I hope the points above have helped throw more light on your thoughts about it. Feel free to drop a comment on how you feel about this and share it with others who need to see this too.

Do you feel like all you think about is him, but he only thinks about himself?
This doesn't mean he doesn't like you. You have to understand how he is wired. Once you do, you'll find there is a subtle thing you can say that to him that will drastically change how he shows his emotions towards you.

Take this quick quiz that looks at whether he actually likes you or not!
