Bisexuality can be very complicated. Bisexuals have feelings for people of their own sex as well as for people of the other sex. The feelings may vary. Some bisexuals have more sexual feelings for one sex than for the other sex. No matter what kind of sexual feelings you have, it is important not to be scared off by them.
Sex is part of every person whether they're gay, bi or straight.
It's also important to remember that you were born the way you are but sexual feelings can always shift later in life. Unlike anti-gay activists want you to believe, there is no definate gay culture, just like there is no definate straight culture. Gays are individuals with different attitudes and different levels of sexuality. There are sexually active gays and sexually conservative gays. Anti-gay activists also want you to believe that being gay is all about sex.
