question: i had sex with my wife before i left on a huntting trip. due to being in the middle of the woods, i did not shower for 5 days. nor did i clean off after having sex. when i woke one morning i noticed 3 or 4 small blisters on the shaft of my pennis. the blisters were extremly easy to pop and had clear fluid in them. healed in about 4 days. there is no discharge from pennis. no pain what so ever. no trouble urinating. i have had this once before last year. same situation. went a few days without showering after sex and there it is.
