i've never had feelings like this for a woman before, am i gay or bisexual or what??? the idea of being with her as a couple is actually really great!, but it could never happen

So what does this mean? i am really confused, i've been straight for all the 18 years of my life, but now what??
I've been thinking about it a lot, and i think my problems with men and my relationships could be because i am gay, i've never had a relationship with a man longer than a few months, and every time its been pretty uncomfortable.
But i don't have sexual fantasies about women!, my fantasies always involve a man and a women. I am still attracted to a few men, i always thought i was just picky!! maybe not??

HELP
has anyone been through confusion like this!?!?

Maybe you are bisexual. It's not a bad thing either. I actually think if I didn't have my boyfriend I would be seeing woman as well as men. I feel silly to admit this, but i do have fantasys of women. However, you could just be bi-curious? I have a male friend who is. He said it's confusing to know whether he's just curious to experiance another man or if he's actually bisexual. He says he doesn't want to have sex with men and fancies woman but he still gets excited thinking about being with men. It's all very confusing stuff. I can't think of a person who hasn't thought they might be bisexual/ gay before.

I believe no one can tell you what are, you need to find out for yourself. Go a bit wild, experiance a woman ( i know thats easier said that done..) and maybe things may be clearer?

Why could it never happen?
I am a great believer that you can fall in love with anyone i am not really into catagorising people into specific sexualities if you meet a girl and fall in love then your in love with a girl and if you meet an alian and fall in love then your in love
You do not need to be confused if you think about it like that. would it be useful to let her know how you feel?
I am in love with a man and have been in love with him for over a year now and my sexual fantasys are about woman sometimes different things just push your buttons.
I felt like this a long time ago but i just learnt that love is love and sex is sex if your not in love with her then you can have sex with whomever you like but if you are in love go for it. Hopefully this helps...stay happy...do anything you can do to be the happiest you can be

^ your reply actually helped me a little bit too! just the whole 'love is love, sex is sex' part. Thats something bothering me a lot lately. ha thanks.

thanks guys, i am starting uni in september so that will be the perfect time to "experiment" and figure out Who I Am!
