Hi there doctor, I'm a 22 year old man. I recently went to the movies with a date and we actually do a cuddle and some kissing. We never use any sexual contact other than doing handjob she did to me. I never done a handjob or fingering to the person's vagina but she did do a handjob like massaging on my genital. Few moments later I discovered a discharge or a pre cum because I can feel something wet in my underwear. Then 3 weeks later when I woke up in the morning, I got a discharge and I feel my pants is wet in the groin area. Is there a possibility if this was a STD of some sort? Because I have nothing to do with sexual contact with anal, oral or vaginal sex because I assume that Mutual Masturbation or Handjob is considered to be the safe sex.
1) any chance that I may get STD?
2) What should I do to keep myself healthy?
