As I'm sure has been stated in this thread. A lot of people don't really see the gender in our head, so much as the gender between our legs. 2 penis' to them means gay. Even if the female is 90% female, that last 10% that is male, is what people focus on. My own incredibly supportive mother even had problems breaking that view.
However, I am still the luckiest girl alive. I seemed to hit it off with a guy, who claims to be straight. Even after coming out completely to him, He is still just as interested as before, perhaps more-so. I asked him very bluntly if he's not at least bi-curious or something, and he claims that he is 100% straight, that he just likes girls. I found that flattering.
There are guys out there for girls like you and I, it just takes some finding. Gotta remember, you can't find them if your not looking. So get out there and look!
