I always get fissures (small cuts) between my vagina and anus after sex... is this normal? I have no other symptoms besides the actual tear/cut itself, and the only time I'm uncomfortable is when I urinate. I understand the fissures are normal, but why do I get them almost every time I have sex? Chemical imbalance? Herpes (hopefully not, but after reading a lot online, it's the conclusion I make)? Rough sex? HELP!
