Why Do Girls Like Gay Porn?
Do you mean man on man or woman on woman?
Sexuality is on a wide spectrum like all personality traits.
Although I never watched porn, I'm a bit bisexual and enjoy fit bodies of both sexes. My first sexual exploration was with a girlfriend at age 14. Since then, I have had two threesomes (two women/one man).
Since my 20s, I have collected wonderful books by gay authors: David Sedaris, Stephen McCauley, Paul Monette, Natalie Goldberg and more. Everyone can learn something about courage and self-discovery.
