Hello. I am 18 years old and have a couple questions about sexual intercourse. I have been having unprotected sex with my partner for about 4 months now...it seems that right before we have sex my vagina hurts. It feels tight and its growing to be very frustrating. I was wondering if this problem is going to go away any time soon or if this is just a little problem.

On a side note I was wondering if my lack of masterbation exercises causes my vagina to be tight...and I am also on birth control...Please help!
