I have only had one sexual partner, who's past sexual partner has no STD's and neither does he. so i started having pain in my vagina A Day before we had sex for the first time. that day i also shaved. Now i have several small bumps along my lips where i had foolishly shaved(and with not a very good raizor either). I know this sounds like shaving blisters but it also hurts when i uranate. these spots hurt very badly and i know they burn when i uranate but the pain is also internal. BTW i am also on my period if that helps at all. I really need help I'm 17 and I'm terrified that I might already have an STD. However I also was giving oral sex for some time before, like a month, so if it is an STD wouldn't it have shown on my lips before now? God I need help.
