I'm hetero, but still enjoy a good cock.
I'm just a horny old bastard who for the moment must replay mental videos.
After living on a beach for years, I found public swimming pool showers extremely erotic: I went every day for a while, on the way to work.
For years I have depilated the root of my cock and pruned the rampant growth: I like to back-stroke and feel only sensitive skin. One particular morning I had just finished shaving and this young feller showed shocked interest in my half-erection. The place wasn't busy, so as I luxuriated under the hot shower I watched him in the big mirror, we were both getting harder. Unfortunately he ran away.
I came very quickly, watching myself in the mirror shooting wildly; at almost the right moment turning into the corner when some guys walked past. A lovely memory.
