I have a massive lesbian crush on my boyfriend's sister! please help?

Hey guys, I'm in a very sticky situation over here, and I don't know what to do cause I'm crushing on her so much! I am bisexual, and 23 years old. The last relationship I had with a girl was when I was 19, which lasted very short. I didn't come out of the cupboard yet. My parents know I'm bi, but I don't talk to them about intimate details of relationships that I have,. They didn't know about the girl of when I was 19. None of my friends know that I'm bi. I am now seeing a guy, we are not official yet. We have been on and off for about 2 years now. He introduced me a while ago to his sister. She comes out with us and our friends often. I liked her immediately, but I didn't have a crush on her yet. We just clicked, and we got along very well from the start. Her brother, the guy that I am seeing, hasn't been clear what we are. Whenever I would ask him, he would shrug his shoulder and say "I donno" My crush on his sister started after I saw a picture online of some girl that looked like two drops of water like her! It could have been her duppelganger almost. I wanted to figure out who it was, and turns out that the girl online was porn actress Dani Daniels. The girl online does also girl-on-girl. So, as you can guess, I watched her porn. Now, I fantasize about her duppelganger, namely my 'boyfriend's' sister. It has taken over my life, and can't stop thinking about her. Each time I see her, I get butterflies in my stomach, and want to kiss her, hug her and so on. I am not only attracted to her physically, but I love her personality too. I loved her personality from the start. The crush just happened. All because I watched some duppelganger porn!!! But what do I do? My 'boyfriend' hasn't been clear of what we are yet. Do I break ties with him and start with his sister? But then what if she isn't bi/lesbian at all? My friends don't know I'm bi either, and are friends with "my boyfriend" and his sister too. so I have no one to tell. Please help me!!!

Just to be clear: I am NOT in an official relationship with the guy. I have asked him several times if he would want to be official but he never answers or says "just give it some time, maybe we will in the future". I call him boyfriend because I don't want to give his actual name, that's why I put "boyfriend" in parenthesis. We are just seeing each other, and it's not official. If he would have wanted to be official, I would have been able to put my feelings off the side of his sister.

  • This is a sticky situation, and one of the complexities of bisexuality. If the guy has a future with you, the relationship may not survive pursuit of the sister, for a number of reasons. Even if he is tolerant, or even intrigued, it could get to a point where it feels incestuous, but probably not at first. in my opinion, you're going ot have to tread water for a while, as you get to know both of them better. While the porn may serve an immediate relieving need, it could also be complicating it all too! I suggest you take a deep breath, tap the brakes, and try to figure it all out. Allow relationships and friendships to develop, and observe the signs, positive and negative, along the way. Maybe even admit to your boyfriend how great you think his sister is... there's no harm in that. Just don't tip your hand yet... you have the knowledge of your feelings, so let it play out!

  • You're probably a lesbian trying to fit into society by having a straight relationship. You should be honest with the guy. If your with him just to feel normal it's out of order. The fact that your lusting after his own sister should tell you everything you need to know. I don't believe in bi-sexuality. You like girls or guys not both. Every bi-sexual I've ever heard of ended up polarising one way when they were eventually honest with themselves.

    • I must admit I do not agree

  • This isn't a lesbian crush because you're not a lesbian. You dont even know if she is queer. What if you break up with him and you tell her and she is freaked out. If you dont want to date you male friend anymore call it quits.

  • Do what you feels best, as you would be always wondering what could of happened. However it's a tricky situation as they are brothers and sister.

  • be honest, and try things out. in the long run you may regret it if you dont

  • He isn't actually your boyfriend... Go after her...

  • This is messed up on so many levels. Even if you did break up with your boyfriend... do you really think his sister will want you?

  • If you break up with him for his sister, that would be fucking heinous.

    Think with your brain, not with your clit.

  • that's f****d up lady
    I guess you should leave both those people

  • have sex with her

  • Put feelers out with the sister and see if she responds to light flirting and keep upping it. Break things off with your guy friend but remain friends. See how things turn out. If your friends are good friends they'll understand

  • stop following ur feelings just cause you have feelings doesn't make them right

  • Why don't you ask her if she's lesbian or bi?

  • Just fuck her

  • i really hope you went for it and it worked out or at lest you got it out of your system, off your chest.

    life is short, express yourself, chase your wants and dreams, be open , what-if's suck!

  • "My "boyfriend" hasn't been clear..." what does that mean? He's your boyfriend. What else needs to be declared

    This is an idiotic question. No dumber than a guy posting "I want to do my girlfriend's sister." Never gonna happen.

    Grow the fuck up you ho

    • read what I wrote, he IS NOT MY BOYFRIEND. We are just seeing each other, he doesn't know what we are yet, and to give him a certain name I called him My boyfriend in quotation marks. Don't tell me to grow the fuck up, and don't call me a ho. I am in love with his sister, there is nothing I can do about it. I don't want to cheap shag. You are the one who should grow up and perhaps read properly what is said there.

    • I have a massive lesbian crush on my boyfriend's sister! please help My mistake. I was answering the question above. No quotes.

  • ... Barf. ...

  • Jesus be the center.

    • Go for it,
