My thighs, genital, butt, and nipples are also very
itchy and
after scratching for awhile I develop larger red
bumps, these are only appearing where I scratch the most.
I don't know if it's anything sexual, but I've been having sex with the same person for two years or so, I was told he was checked for STIs after his most recent girlfriend, and as far as I know has only had sex with me since then. Problem is he is itchy too, not so much the rashes and bumps.
