Hi, A month ago I went to a massage place and unfortunately, a very different massage place. I did not go there with intention of sex, however it ended up with my penis touching her vagina and very brief intercourse. I freaked out and washed myself with hand soap 3 times shortly after. 8 days later I got this tingling feeling in my penis. Comes and goes and it is in different places, sometimes it is inside urethra and goes all the way too anus. I took IgG and IgM test about 10 days later and both were negative. I was also prescribed acyclovir 400mg in case of out break which I took for few days, but no difference in tingling, so I stopped taking it. I also have a slight lower back pain. Is it possible to have 3 weeks of tingling and no visible sores? Can Acyclovir stop the first outbreak? AS I mentioned it comes and goes and It is not always at the same spot. I kindly appreciate your response.
