I'm 19 years old, I lost my virginty last year, but his penis wouldn't stay in my vagina? He popped my cherry and I bled loads.. But it wouldn't stay in!  I've been with two other lads since then and the same thing has happened.. Why won't it stay in? Am I too tight? Now I don't want to be with another lad because I'm scared that's going to happen again.. Please send me your thoughts never told anyone this.. :/ :)
