I seem to fancy my boyfriends older brother. :(

I know that its wrong but I can't help it! Hes really good looking and so sexy (so is my boyfriend, don't get me wrong!) and I find myself really attracted to him and I also feel that he might have a thing for me, not a big thing like but he's always touching me when he gets the chance and he's always teasing me. Hes in his twenties and me and my boyfriend are in our late teens. Im crazy about my boyfriend and I am attracted to him but Im always thinking about what sex with his older brother would be like and fantasising about him. Now I would never act on this crush of mine because I LOVE MY BOYFRIEND SO SO much but secretly I'm kind of hoping that he grows up to look like his brother. Im always hoping that his brother will be in the places that we go to just so I can look at him and talk to him. Is this so wrong? I DO love my boyfriend more than anything but I DO fancy his brother too ... anyway I can get over this cruch?
Please help!

All advice is helpful..

(But don't be too mean because I can't help it, I really am a nice person and would never do anything to hurt my boyfriend.. we have been together for 2 years)

Thanks ! :)

I guess as long as this is just a fantasy then it should be harmless.

However allowing him to touch you is not harmless it could be classed as leading him on.

Don't act on this fantasy because if you do it will cause untold damage to your b/f and his brother and their relationship, and also yours and the 2 brothers relationships.

Its dangerous and could prove very drastic if you ever act upon it, how can you be sure that if in an alone situation with this older brother you wouldn't succumb to temptation?

I would think you could very easily be tempted.

Just ensure you never allow this to go any further. No matter what if you find yourself alone with the older brother, make an excuse leave the room, go home, anything. If you give in to this fantasy, and let it become a reality, you'll find you end up very very hurt and could cause serious damage between these two brothers...

No, it's not wrong. You're human, you can't help it when stuff like this happens.

Yes, you can get over this crush by avoiding him. That is the only way.

Don't see him when you don't have to. Seeing him will only peak your curiosity, but if you don't see him much, you will have less things to think about. So keep the brother out of your life and focus on your current relationship.
