My bf only put the head of his penis in when we were fooling around. Said he tried to pull out before he came. Is pregnancy still possible? I'm a virgi

Yes, possible. "Tried" to pull out implies he wasn't successful. Ejaculation in the vagina or on your genital area was high risk for pregnancy, especially if you are mid-cycle. Get professional advice and/or go to a pharmacy today for Plan B contraception -- ideally with professional advice from a clinic, e.g. Planned Parenthood or your personal physician. Good luck.
