I know a young man who is gay. I warned him about the new strain of HIV,etc.etc.etc. He's celibate right now (thank God). It's all a lot of self hatred. Just thing about the sex act itself, which strikes me as being an act of assault against the human body. There are many homosexual people, especially men, walking around with a lot of self hatred and no love for themselves. The only gay men I've met that are happy have been with their partners for years. These days, it's a lot of promiscuity and a disregard for life.
I don't think any promiscuous people are happy, whether heterosexual or homosexual. When you value yourself, you expect someone else to want you exclusively; when you don't value yourself, nobody else will, either.
I had some homosexual friends in college. I still pray for them; they were nice guys.
