Is it possible for an std to show up after 1 year?

[hypochondriac]

Hello- I'm a hypochondriac, meaning I excessively worry about nothing. Heres my story.

I messed around with this guy over a year ago, during a break up with my monogamous partner of 4 years,non protected sex, and ever since I've been worried about having an std. 3 months after him, I had white coating in the back of my throat and I thought I had hiv. I got a mouth swab test for hiv 4-5 months after sex with him and it came back negative. Here it is, 1 year and 4 months later, I have vaginal itching (light) and some redness on the inside of the lips, with a pimple like bump. I was able to pop it. I also have a hard bump on the outside near the panty line and I think its an ingrown hair. Could this irritation be from too much baths or masturbation? Is it possible to have an std after a year of possible exposure? (I got back with my boyfriend a couple months after that and he never showed signs of infection.)

Very unlikely. The itching is probably some simple vaginitis we all experience. You seem yto have the rest under control.
