I have frequent intercourse with my very well endowed partner, something is definitely wrong in my vagina. I m a very healthy, physically fit female, in my late twenties. We are very exclusive (no other partners). It hurts to have intercourse, TMI: there s a lot of irregular discharge, a very bad odour (despite me bathing several times a day with vagisil pH balanced wash) and there s just a different feeling with sex all around - what could be wrong?
