There is absolutely zero chance of you getting an STD from this encounter. That includes the handjob, the touching, the oil, the towel, the table, etc.
If you have warts, it's not from this encounter. Warts have an incubation period (time from infection to when you see symptoms) of usually a few months.
You do sound like you might have a prostate infection, though, and that would be coincidental. The tip of your penis hurting, the abdominal pain, etc - this could all be from an infection in your prostate. You should get this checked by your doctor. Perhaps the oil got into your urethra and has caused an infection, perhaps it's coincidence.
I don't know if you have a hemorrhoid, but that would definitely be a coincidence, too.
All of this seems to be such a anxiety fuelled coincidence.
I don't know if I have a hemorrhoid or if I have herpes / anal warts?
Could light rubbing around my anus have caused anal warts of any kind? Or is this a huge coincidence and I've developed a hemorrhoid?
