I am a 21 year old man and never had this problem until I started dating this 24 year old lady named Betty about 6 months ago. I met her in a bar and slept with her in her in the parking lot that night. Now for the last 3 months my private member has swollen, turned red, became sore to the touch and it burns severly when I urinate. Betty is the only person I have had sex with in the last 2 years, ( I was in the Navy for 18 months before I met Betty and did not have sex ). Betty swears she has been tested for std's and has none, she also says she hasn't slept with anyone else but me, but she has been going on a lot of overnight trips with her family members lately. Or at least that is what she tells me, for all
I know she could be off with other men, because I have caught her in lies before and she never wants to talk about her trips when returning home. Could I really have an std? Or do you think I may have a urinary tract infection and just need some antibotics like Betty insists?
