Hi I m 32, I got an sti 9 months ago, had a long course of antibiotics . I was ok for a while but then I started to get a slight stinging in the tip of my penis after sex only. So I thought it s only because of sex. My partner went away for 2weeks, so I had no sex, but then my stinging pain got worse, it is like everyday and night, I went to the gum clinic and my results came bk negative. I ve spoke to my partner who get abdominal pain after sex, but science she s been away and had no sex she has had no painor symptom. Pls help me and were can I buy antibiotics with out seeing a specialist?
