what could this be ? ive been upset for months

Five months ago i had unprotected sex ans experienced burning from urethra when i walk , itching in the inside , sore urethra and these two red spots on it and the left side of my lymph node in groin was swollen . Then a few days later i got friction ulcers on my posterior forchette from sex. All my symptoms would go away and then come back so i decided to go to the doctor and she said i had a UTI ! but after i would recieve vaginal ulcers after sex and my urethra would be inflamed and hurt really bad , depending on position. i took a vaginal swab test and it said if it cant detect bacteria or acidity then its probably a yeast infection File size is too bigFile size is too big
