Well, gay sex kind of directly harms yourself with a plethora of diseases, sooo.. yay, it harms you/your partner. (jk)
You must be 12 or something. Any sex would harm someone if they had diseases. Me and my partner are completely clean and careful, but thank you for worrying about my health
honestly though, "I disagree with the lifestyle but still respect them" basically just means they're a homophobe but don't want to fully admit it. If she disagrees with who you love and doesn't think that you should be treated equally under the law and lives her life according to a religion that says gays go to hell, how can she possibly respect you?
