... He has had them in the past and they have seemed to go away on their own. A couple times they appeared on his shaft. He says they cause no itch or pain. I was tested for stds a couple months ago during a routine exam and all of the tests came back negative. We've been together for 7 years and as far as I know, he has not slept with anyone else besides myself in that time span. What else could the bumps be ?
