So me and my bf had unprotected sex with my shorts on. And a couple of days later we had sex again and I looked at his penis and noticed a sore , he claims it s a rug burn / friction burn from rubbing up against my pants and that it happened before but not in the same spot but I freaked out as a normal person would and assumed he had herpes or some sort of std because I never had that problem and it was a freaking sore on his penis . I Google searched some pictures it didn t look like a rug burn but more of Syphilis . He then got a scab on it later it was white around it and a few days later it healed but I m still scared it may be an std . Its soon to be 4 weeks later and I m getting checked still but Please help . Am I over reacting or is he lying ?
