Please help me I cant feel my boy friends penis go in me any more
the only solution i can tell you is to have a rag handy so you can wipe away any uwanted wetness it works for me your boyfriend wont mind you trying to make the experience better so it shouldnt take away from the moment.
You could try "pelvic floor exercises" to tighten you vaginal muscles, Google it; some women use a Kegel bar to strengthen these muscles.
