hello, so I went on a trip to do some military field exercises for a month and the last week I was outside for a few days. I was on my period and we had no tissue in the port-a-potties so I couldn t wipe for two days. when I got back I noticed I had two little canker-like sores on the tip of my vagina and they sting when I wiped or touched it. I washed well after leaving the place but my boyfriend of a year insisted on having an intimate night. we had oral sex and actual sex but he ended up with a few sores on his mouth and little canker like sores on his penis a few days later. I have only had sex with him since we ve been together and prior to my sores we hadn t had sex in almost a month. what could this be???!?
