Okay so, this might be weird or a dumb question but me and my fiance did not see eachother for two months and when we did we had sex 30 times or more in 6 days. When I got back I got my period and I noticed what looked like a pimple on the outside lip and what looked like a rug burn on the other. Is this from too much sex or what is going on? I know neither of us have any STDs because we only sleep with eachother, so what else could it be?
