okay so in early july i had sex, once only, without a condom! my first and only time.. and maybe the biggest mistake of my life. this past month or 2 i get these outbreaks of red itching bumps on my private area. they get worse after i shave and itch mostly only then, but they seem to stay all the time they just dont itch and they go down a lot.. also last month 10 days after my period i had brown discharge for a few days, this had only happened 2 times. i asked the guy and he says that he goes to the doctor often and gets checked for STD's and he said he doesnt have one.. do you think i do? what should i do?
