After receiving prolonged oral sex 8 hours later I had alot of yellow discharge,slight painfull urination, It has been 2 days the discharge has changed to clear but it is still there although alot less than it was.(I self perscribed 100 mg of doxy *2 daily later the next day about 4 hours after symptoms started) What do you think this may be from? I have had the same symptoms after oral sex was checked for stds and they found nothing but still ran me thru the gammut of 2 weeks doxy and a shot of the painfull stuff. I have also had the same symptoms after grinding with no underwear on my part but she had some on. I have slight testicular pain and have had this before during these other episodes. I later went to a uroligist and was told I had a small cyst in my epidimus 2mm and not to worry about it.(he said thats where the pain was from)I had been diagnosed with epiditimitus 10 or so years ago but have had no other issues with it until recently and was not told thats what it was. The first time this happened(1 1/2 years ago) My ejaculate volume decreased substantally and has never returned to what it was the urologist said it was because I was older(Im in my mid 30s)
