1st Time having sex

Despite all my blogs and my super horniness, up to 11th grade I had not had sex, had a few girlfriends but not sex, started dating a girl that lived next door and she was my 1st sexual experience , I lied to her about not being a virgin, but when we 1st went to do it I did not know what to do and I could not get it in, after about what seemed like forever I finally got it in and instantly came, we had sex a few more time and she left me for my best friend. she never took her bra off so I never seen her titties we never had oral.
