How can I deal with jealousy?

So I've noticed that I'm very jealous(or envious) at other people, espicially at other gays. Like when they talk about their sex life and how many hookups and sex partners they had while I'm 16 years old,still a virgin and never had a boyfriend or even my first kiss. I get a big hate feeling from that. Also things like someone having a better house/apartment or education makes me jelous too. Same goes for someone who's better looking.Has anyone ever felt the same? How did you deal with it?
