a warning (i dono how bad my post really is, i did my best to keep it serious and profanities free, but just in case)

so i am really, REALLY horny. i am 20yo,have a bf, still a virgin and i am also terrified of sex. but omg i wanna have sex. i feel the physical need. I'm not pressure by the society or my peers. there is no pressure to have intercourse except when i get pressure inside, telling me i want some effing friction. am i alone? is everyone doing it besides me? how do i deal with this?! how do i over come my fear of closeness and being open w/ another human being on intimate level?
tips?
