Well I spent one night at her house... things were cool until we woke up in the morning... and I guess she put in 21 jump street and well about 40 min into it we fell asleep... but we were holding hand and snuggling each other... it felt like 15 min when I woke up again our faces were touching.. lips were in contact but nothing happened for about 5 min until imade the move to softly kiss her.. she was asleep but I'm guessing she soon woke up, cause she started to kiss me back.. for 5 min we kissed and kissed pulling her close to me.. until I thought... that's my because I should stop so I pulled away. And for a minute we stopped but she went out and kissed me again and we just nade out for a good I don't know 15-30 minutes constantly moving my hand around her body and her pulling my head closer... until someone knocked at her door and I had to push her away.. I liked it but she's straight and I'm the open bi because... it was awkward but it just went on as a normal day.. I'm not sure if she knows we kissed... but I do... it feels wrong but it felt so right at the same time.

She says she's straight, she's your cousin, you both are teens, she may or may not remember the touching, she may have just been doing teen experimenting - let it go. It's not 'wrong' but you are better off not sharing a bed or bringing it up.

Yes, be very careful, don't repeat the episode.

Leave your straight cousin alone. It's a bit tacky. No more sleepovers.

I agree with leaving her alone. She is your Cousin! Don't sleep over any more either. This might have been fun, but it was a "one time thing". Let it go. Meet some other girls. Smile, and others will want to meet you!
