Basically, I masterbate once, maybe twice
a day. Recently, I have noticed what
looks like swelling or inflamation on the
left side of my penis, under the skin,
where the shaft meets the head. It is not
a blister by means of exterior skin
abrasions, it looks like it is happening
under the skin. Is this caused by
excessive masterbation, rubbing to hard or
the wrong way? It seems that if I stop
for a couple days the swelling goes down,
but the next time I do it, it swells up
again. Should I just lay low on the
masterbation for a while and let it heal
or is there a serious problem. I should
add that i've been with the same partner
for a year and a half now, been tested for
stds and was normal and so was she.
