I've been sexually active with one partner for just over a year, in the last few months i've noticed after having sex just at the entrance of my vagina there are 2 small lumps that have been growing bigger. The are un-noticable most of the time only very small. However after having sex they expand to the size of a small marble and are blood filled and hard to the touch. They aren't painful but are worrying me alot.
Neither my partner or myself have been with anyone else during our relationship, but they continue to remain there are they don't look normal.
Any suggestions as to what they might be?
