It has happened to me twice in the last month: I was sexually arosed and the usual watery fluid (I think from the prostate) discharge happens (I always used to have this, before ejaculation), I felt some mild pain on the lower glans. After I urinated the pain passed away. I wonder if it is an STD or UTI. I haven't had any sexual contact for about 4 months; even then I used condom. Can you think of any disease to much the symptoms? Thank you
