Hi... I'm acutely aware this is absolutely disgusting, and I have grown up A LOT since this happened. This was the best part of 15 years ago, but it's just now come back to haunt me, and I'm not sure what to do.

When I was at college, I was VERY sheltered and naive about anything to do with sex, STDs... anything really. While cleaning our shared dorm, I found a vibrator belonging to my flatmate. I used it, once, because I was stupid and curious. I did clean it, but felt horrible after, as I know I should. There's no real excuse though, I know.

At the time, I was a virgin, and she wasn't. Point is, this memory just got unlocked, because I've been dealing with some horrible health problems that no one can figure out. Nothing is coming up in any other bloodwork.

Maybe worth saying at this point that I'm actually still a virgin, (there are many reasons why, including psych trauma from attempted assault.) But I've never actually had an STD test.

Point is, should I get tested? Is there even a chance that some disease could have been on that vibrator, and not shown itself until now? It seems a reach, but I just don't know, and am terrified now it's occurred to me.

Now this has all come up in my mind, I also feel like I should confess to my old flatmate, but after over 15 years, what would be the point? I'd definitely lose her friendship, which I treasure more than I can say. (And since I'm pretty certain, being a virgin back then, I couldn't have passed anything on to her, especially if I cleaned the toy? The idea though that I could have done, despite being a virgin, horrifies me.)

Ugh, I feel like the worst, most disgusting person ever typing this out. But I'm so scared and hoping someone could offer some advice without too much judgement please?

Thanks

TL;DR- Used someone else's sex toy once, 15 yrs ago. Could I have caught something from it that's not caused issues til now? (Yes I know how absolutely gross this was to do. 1000% regret it.)
