Hypochondriac

Y'all I don't know what's wrong with me. I am so terrified all the time of contracting an STD. I swear, if I cough, I must be sick and have herpes. It sounds so ridiculous but it's true! Lol last year I had sex with this guy and after we were laying there and I noticed a bump in his pubic area. I asked him what it was and he said he didn't know it was like a mole and he's had it even before he was sexually active. Of course that's a good explaination and it would suffice for most but no. Ever since then I have freaked out every time I develope a pimple or any sort of bump down there and concluded its a wart. I feel like I'm losing my mind because of this anxiety! I check down there often with a mirror and inspect and awhile back I noticed a tiny tiny bump (if you can even call it a bump) near my vaginal opening and anus. I concluded it was just a little bump perhaps a skin tag that was nothing. I had a slue of hormonal issues including estrogen through the roof and noticed later that the bump had grown like 3 times the size. I freaked of course and was online googling genital warts for hours on end and really couldn't find anything that looked like what I had. If you stretch the skin it's hardly noticeable but if it's loose then the bump is very noticeable. It doesn't have a cauliflower appearance and I even tried the vinegar test and nothing. If anything it's probably a skin tag but mainly my point was does anyone else go through this ridiculous unnecessary anxiety about something that probably doesn't even exist!? I used liquid nitrogen to burn it off so I'm still healing. No pics of what it used to look like. I regret not taking any.
