I often get tiny cuts in this area after rough sex (from spreading that area too wide) and it being rubbed too much which irritated the skin which usually just sting a little when I pee but usually go away in a few days after using Neosporin. But this time its slightly swollen/sore; which i noticed after it hurt to poop like a burning feeling(which could be due to the fact that I had coffee for once & they added regular dairy milk which i don't drink). 

I also often get yeast infections (like once every 2 or 3 months). & i did notice discharge today as i was examining the store area, so i may be getting one.

I was just tested last month (april 3rd) for every std & that came back clean. But im not sure if i couldve caught something since then.

Do you think it could be an std or just a bad reaction to rough sex + the start of a yeast infection?
