Alright I'm 18 and I naturally have 6in girth. and i've tried having sex before (with virgins or damn near) and I either could not get in or she refused saying I was too big. I try to get them wet, foreplay, fingering, oral but and keep them relaxed but they just tense up. I'm aiming at getting a more experienced girl but there is another virgin in my life at the moment, any help?
