Remember, although anal intercourse does not cause pregnancy - unless ejaculate or pre-ejaculate is spilled in the vagina or on or near the vulva - unprotected anal intercourse is high-risk for many sexually transmitted infections, such as gonorrhea, HIV, chlamydia, syphilis, herpes, HPV, and hepatitis. Each of us has to answer these questions for ourselves, but it may take time before we can answer. It can take years to understand our sexual orientation. Sexual orientation - being lesbian, bisexual, gay, or straight - is about sexual attraction. Some people enjoy anal sex, and some people do not. Many men and women enjoy anal stimulation, regardless of whether they’re gay, lesbian, straight, or bisexual. I heard someplace that anal sex is for guys who like guys, if I want to have anal sex with a girl, does that mean I am gay? Am I gay if I want to have anal sex with a girl?
