yes, we have all been curious at one point or another, i find women attractive, i admire beauty no matter what the sex. i have thought sometimes 'if i were a guy, i would' to me it is natural, particularly at a young age, when you are not sure, the longer you leave it the more the curiosity grows
and finding lesbian porn a turn on isnt rare, i agree with sydney123456 here.
the fact of the matter is that we like the idea of being with a woman because we think that they would know our body and know what we like because we think it feels the same for them.
we have the feeling that they know the where why and what. that i think is what it boils down to

and porn is good for stimulation and imagination but when it comesdown to the crunch, would i sleep with a woman-NO...
I am comfortable with my sexuality but understand respect and like gay people and bi people for who they are, what sex you like does not determin who you are...so dont worry about it, just do what feels rite for you
