Hi,

i masturbate everyday before bed. Recently, I have seen little bubbles pop up around the corona of my penis. They are in clusters. The first time I saw it, there was only two. I accidentally popped them but there was no blood or ooz like substance that came out. Just a clear watery substance. After going to my doctor, he said 9 out of 10 times it was just because I was masturbating too hard and it was fluid build up. That was a week ago. I decided to test the waters and do it again for a full week. Now I have a cluster around the same area. They don't itch, burn, or sting. It just popped up there. Do you know what's going on?
