Do you think it's okay for a guy you dated to go out with your sister?

Yea -- that's kinda shitty.

I definitely think it's wrong. She wouldn't like it if you dated her boyfriends. She needs to not be so selfish. There are PLENTY of guys in the world. Why would she do something like that, that she knows will put a wedge in between you two?

well lets just say this guys name is cartez and your sisters name is jessica then that's just not right if you ask me who ever dated him first didn't do anything wrong,but if your the one who dated him last then you werent being very fair(if you went out with him last and you didn't know it but your sister kissed him and then you kissed him,thats like you kissing your sister.thats just one reason why you wouldn't want to do that.)

No, No, No, No!

A few years ago I was dating this guy, mostly talking on the phone. It was at a time in my life when I was extremely busy so I really didn't have time for a relationship. We just kind of lost touch and a few months later I'm over my older sister's apartment and I answer the phone (Shocked to hear his voice) When my sister got home I let her know that we dated for a while and she immediately called him and let him know not to call her anymore. We never slept together or anything like that but it was still weird.

Yes, I agree with you completely it's wrong. You're sister's! I can't even think of doing that to my sister. Doesn't she know that there are plenty of guys out there she can date? That's weird.if she keeps doing that your relationship will get a little rocky if she keeps doing it then you should talk to her about it.

Yes! It's only ok if you were totally ok with it and I mean completely. If not, then yeh it's completely out of line

yeah its wrong. that sucks both on her part and on ur ex boyfriends part

I say that is very wrong,why would someone do that?its like he was with you now he's with her weird.
