I'm a 35 y.o. male. In late January, I was given unprotected oral sex by a woman ( random, one night) for no more than 5 minutes. After a day or 2, I started to experience a burning/tingling sensation on my penis for the next 3 weeks or so, with no blisters or sores. I went to a urologist, and he seemed to think it was all in my head and said i had nothing to worry about. The sensations then went away soon after. 3 months later I started to experience the mild burning sensation again for the past 2 weeks, with no visible sores. Does this sound like genital herpes?
