A bisexual is a person who is attracted to and has sexual relations with both men and women. Feeling attracted to your own sex and also the opposite does not necessarily mean you are bisexual. Human sexuality is complicated. If you think you may be bisexual, talk to a person you trust or a psychologist for counselling. What everyone must know is that ANY sexual activity where body fluids are exchanged puts you at risk of HIV. Anal sex is extremely risky because the anus is tight and can easily tear, so sex between men transmits HIV more easily.
