14 days ago I visited a massage parlor. Probably the dumbest thing I've ever done. After a table shower I received a hand to genital happy ending. At the end she was using both hands. No oral or penetration at all, and no body contact other than her hands. I immediately went home and took a shower. ( I was already regretting everything) about 4 days latter I noticed some discomfort at the tip of my penis, and it has continued to come and go. No discharge at this point, but some discomfort off and on during urination. My questions are. Could this be an STD. Could she have caused trauma during the handjob. Should I get tested.
