Is it normal that i get jealous when my boyfriend plays around with his sister?

That's really not normal at that age - when you grow up, playfighting is a sign of flirtation. They probably aren't incesty or anything, but that would make me feel super awkward. I have an older brother and we used to playfight all the time, but aside from the occasional dead leg or arm we don't do that anymore, just because it would feel... WRONG O_o

Your boyfriend should really be playfighting with you not her. It's totally something he should grow out of and accept that both he and her have hit puberty, and therefore can't do things they would have as kids. It's alright to take a bath and run around naked around your siblings when you're little, but doing that now is sick. Playfighting is just a bit more pg-13, but the sexual undertones are there.

You should make him watch the Friends episode with the innapropriate sister. Episode 510. Do it.

Do you have any siblings?
If you do you'd be able to understand.
Its not incest or anything their just doing what brothers and sisters do...annoying the hell out of eachother as others said

Mm and why don't you initiate the playfulness with him ;D

Your bf and his sister have known each other their whole lives, they've probably grown up teasing each other and fighting, it's just how siblings are. Believe me, I have lots of them. So you're 18, assuming you haven't been with your bf for long, he is probably still finding his feet in the relationship and doesn't know how you would take his more childish side if it were directed at you.

So instigate - tease him, refuse to give him something and make him wrestle it from you, tickle him or something and see where it leads.

Do you think he has a physcial attraction to his sister?

Personally...I think you need to grow up. It's his sister...siblings do these things. If I were him, I'd say "excuse me??" and dump you if you let on you're jealous.

It is normal! I get jealous of the way my bf is with his cousin who is very pretty!

That's how he relates to his sister. They share a bond that you don't share with him. Stick your lip back where it belongs and realize the sun doesn't rise and set on the crack of your a**

lol this is amuseing.
Incest is the main thing on you're mind right now isnt it? lol. Who knows maby they do like each other. But siblings usely dont act on this. There adult siblings that have a larg bond. Its normal that they act like children time again because to each other thats what they are. You came into there world an adult. Only natural they treat you one. Dont be jelous, funny as it is, its wasted on someone that isnt going to "move in on you're man" as some would say. Though theres always the chance they could act on sexual feelings, its not likly. BTW the last thing you want to do is create sexual tention between them. If you're going to say anything, make it clear that you want the same "playful friendship" they have or something. Letting on that to you there actions seem sexualy driven may build tention and curiocity. Thats the last thing you want.

Good luck

It's weird that people immediately jumped to boyfriend has feelings for his sister...that's just how they bond. It's normal that you are jealous that he's giving her attention. I'm sure if you wait and get closer, he'll feel more comfortable around you and might do the same thing.

immature, that's the answer.

Well your bf pretty much knows her sister from birth, so he's alright by the way he treats her.
Will you like it if he does those annoying playful things to you?

When girls have no sisters to play with, and boys have no brothers to play with, they often act like a couple of puppies. My girlfriend learned to tackle like an NFL linebacker from her one and only brother.

If there's an age gap and he's much older I could understand, he probably still sees her as his little sis, but if they're close in age, then I find it odd.

I have sisters and as kids we play-fought but the touching stopped during the early teens/puberty.

Not sure what's going on there, but if were you I wouldn't be too jealous, even if she's very pretty. Unless he has an incestuous relationship with her.

Me and my bro still tease each other and we're 21 and 24. We're best friends and probably would be if we weren't related. If my brother's wife was jealous of our bond, he'd probably file for divorce. No lies.

That's somehow normal that you feel this way, but you shouldn't think any furthere. I guess he does that ever since they were younger and the fact that they still do such stuff only means that they have a close relationship as siblings? My brother does the same thing to me, it doesn't have anything to do with incest and all that crap. If you want him to do the same thing then show him that you're into such things? Try do something similliar to him to give him a hint?

I think you just feel this way because you wish he'd give you some of the attention. That's not a crime, you ARE the girlfriend.

But don't be jealous. That's his sister. I highly doubt he's doing anything bad, and if he is, well he's just a sick freak now isn't he?

Just talk to him about it. You don't have to mention that you are jealous, but tell him you'd like some of that treatment. I'm sure it wouldn't be a problem to him, in fact he probably wants to act that way towards you, you just seem like you wouldn't like it.

Wow.

Don't assume that they're flirting. After all, that would be INCEST.

Anyway, to get him to do whatever you want him to, you need to start the whole playing thing. He'll probably respond by doing the same and then he'll switch from annoying his sister, to 'annoying' you.

Don't mind him, he's know her for a long time, and thinks it normal. you are only getting jealous because she is the same age and you "think" shes a lot prettier. Remind yourself, she's his sister, does she have a boyfriend?

i hate my sister too!

There is nothing incestuous about this (to reply to above comment)!

You love the spontaneous and playful relationship he has with his sister. That's great - tell him!

You are a lucky gal to have a guy who - through his healthy and fun-filled relationship with his sister - knows how to enjoy being with people period, whatever their gender.

Cherish that, and play with him too - he'd be tickled pink, especially with someone so extra special. You go girl!

If you want to be picked up, let him.
this isnt normal, but its okay.
You cant have the same bond with your boyfriend that he does with his sister.
it's not the same thing, just like she cant have the same bond with his sister that he can with you.

WOOOOAAAAAHHHHHHH!!!!!!!!!!!!!!
Get rid of that guy, never go out with a guy who likes his own sister!!!!
Believe that, any relation you have with your sister should be a hug and a good night, and than get mad at each other.
If that guy is hittin on his own sister, believe me, he is a creep!!!
It ain't normal cuz it doesn't happen.
