This is one of those 'I really hope it's just a rash' things-- I am calling my gyno tomorrow! I have been intimate with new boyfriend for the past month, we've always used codoms, but put them on just prior to intercourse- which means that we have had some skin-to-skin contact just prior.. I had my period last week, nothing unusual except when I was on my cycle (spinning class), I felt this painful sensation, like I must've rubbed something while on the seat- I had a tampon in and thought it may have been the string, plus underwear friction on the (little) seat. I stopped workout short, obviously (!). Later in the evening while urinating it was burned so I looked closely and did NOT see any sores, just a red mark on my left side labia- like rubbed it raw. It's now four days later, I can only see a little scab-like something. On the right side is a little red mark but again, no sores. I haven't experienced what seems like the 'classic' symptoms: back/leg pain but I do often have post-period headaches which is not unusual. I did notice once on my partner a 'bumpy' area just under the head of his penis but it was totally under the skin and not red or broken skin. I have had cold sores on the lip on off for 20+ years and have read that one canno be transmitted to the other.. any advice would be SO appreicated :)
