Question: I'm not sexually active yet but the other day I used a vibrator to see what it was like and my problem is that it wouldn't go into my vagina at all. Could it be that I am "tight"? I can use tampons with ease. Is there anything wrong with me? And how can I fix this problem, I'm worried that when I do have sex with a guy that his penis wont be able to enter my vagina at all. Thanks for your help.

Answer: I am sure you are perfectly normal. Your vagina is a "potential" space, not an opening or hole in your body. Your body must make room for whatever enters your vagina. I suspect that between your hymen and pelvic muscles, your body in not ready for the insertion of something as large as a vibrator. You are correct in wanting to make sure your body is prepared for intercourse prior to actually doing it. Please see the pages about Virginity in the Intercourse section for the information you seek. Information on preparing the vagina for intercourse is presented there.
