I am a straight 47 year old white non dug using circumsized male. I have had about 6 sexual partners in the last 3 years. Always Condom protected for vaginal but no condom for oral. Always recieve oral never preformed oral. Non of my partners we csw. Last encounter was about a year ago. I tested for HIV about 18 months ago and was neg. But after reading all this stuff on the net I realized I have not been tested for STD's besides HIV. now I have not had any encounters in about a year. and Never had any symptoms or anything , no warts no puss no discharge, no lumps no sores no anything. My question is there any std that I could have that would not show any symptoms in over a year that I could have gotten from recieving unprotected oral. I read in one of the post that some symptoms would have shown up by now a year later. And should I run out and get tested ? thanks for your time ...
