Anal Fingering - STD question

[anon2323]

Several days ago I briefly fingered the anus of a woman while sitting in a hot tub.  Also while in the hot tub she briefly stroked my penis with her hand.  Other than this there was no contact of any kind.  Shortly after leaving the hot tub I washed my hands with antibacterial soap.  I do not have any open cuts on my body, and she did not appear to have any.

This week I am experiencing a 'tingling' sensation at the tip of my penis.  I would assume my chances of contracting an STD from my encounter are low.  In addition, there are several other things I think may be the cause of the irritation at the tip of my penis: several days ago I shaved my groin, and my penis is rubbing against short / prickly hairs on scrotum.  I played soccer since the incident while wearing shorts made of abrasive material and no underwear, and felt some chafing during the game.

Once I felt the tingling sensation in the tip of my penis, I became concerned about STDs.  However, given the type of contact I had, and the other factors that could very well be the cause, what are my chances of having an STD?

You has no risk of getting an STD from your encounter. Masterbation (masturbation) is not going to give you an STD.

its probably just a little chemical irritation from the chlorine in the hot tub, it happens

You had no risk. Take care.
