Okay I am 23 yrs old and I have never had any STDs or anything the only biological issue I had that was sexually transmitted was i think STI and cured with antibiotics. kind of like a urinary tract infection it went away no issues. but....I have the very gross odor similar to a yeast infection smell i guess. when i was 16 i had a really bad cyst that just happened to disappear...Ladies anyone have an issue or had one like this? i would say it started when i hit my 20's it just feels terrible, its not painful but i just hate not feeling clean. it gets worse around my cycle i think. should i start taking vitamins? what are good ones to take? and my last STD screen was in Jan and nothing.
