Had unprotected sex almost 3 years ago. Tested for Almost everything, and all was negative. Only thing I’m not sure is trich. Have had no symptoms apart from mild yeast infection which goes away with canesten. I read about it for the first time 3 days ago, and now have a strange tickling sensation inside the penis ever since. Question: could I still have it after being probably asymptomatic for 3 years and then it suddenly shows symptoms (but no burning, discharge, smell)? How likely is this? Doesnt it normally go away by it-self in males? Could my partner develop symptoms after a similar length?
