I think I have a crush on a younger man
Why are you so attracted to him?
I don't know, it feels like I've always liked 18-year-old guys.
Well as long as they are of the legal age, I see no problem. Some people just prefer to date people that are younger than them.
I just want to kiss him.
Well as long as you get consent first then it would not be a problem for anyone. Try to keep looking around and find someone to crush on that is around your age though.
