Hello. I have been completely monogamous with my wife my entire life. However, a month ago on a business trip, I was with some swingers . This woman touched the penis of a couple men, then gave me a hand job. I fingered her vagina by putting the tip of my finger in her. I did not have intercourse of any kind (oral, vaginal, or anal). It was mutual masturbation that lasted about 5 minutes. I took a shower immediately after this. I am very worried about having picked up something like genital herpes. Is that possible from what I did? Should I get tested?
