I visited a health spa two days ago that includes a men's only section for hot tubs, massage pools and saunas. No clothes are worn and all guests are required to and do shower before entering. All of the water is chlorinized (blue). I had a breif encounter with a man while in the hot tub. He placed my hand on his genitals and I stroked the shaft of his penis for about 20 seconds. He rubbed my crotch then rubbed and pressed against my anus with his finger (seemingly trying to enter) for a couple seconds. His finger nail scratched a little. I stopped the situation and nothing else occurred. I have some feeling of irritation on my anus. I've had HSV-2 for many years. Has this incident put me at risk for any STD or other type of infection?
