IM 19 and a guy. I have been having sex for a year and I haven't gotten any pleasure from it. My girlfriend orgasms but I haven't had any good feelings out of it

Do you masturbate frequently? If so, how you pleasure yourself is more predictable then having intercourse with a woman. If you do masturbate a lot, you need to back off that and get back on track so you can enjoy a proper sexual relationship with your g/f.
