I work out regularly at a local gym, but I'm still on the pudgy side. I started working out a few years ago when I got a scare from a racing heart, I ended up with an ER visit, and then a trip to the cardiologist for an EKG. The nurse shaved half my chest and several spots on my arms and legs; this felt really strange, so I shaved the rest of the way just to make thing even, and found I liked the feeling of bare better.

I've kept cleanly shaven for the last several years, and work out regularly, so I'm pretty fit. Recently I started treatment for an enlarging prostate, the drugs have a very strange side effect. They are making my nipples larger and stand out almost all the time. The Dr says that is only temporary and will go away after the treatments are done.

Any ways what is strange now is the shower room at the gym. I've always showered there and now pudgy me with my "man boobs" and now very large erect nipples I'm a little self conscious. Last week I was in the shower and a couple guys join in, very common to have multiple guys in the shower, but after one of them left I noticed my shower mate was sporting a very large hardon. I went to leave and he started up a conversation. Which seemed a little awkward to me taking naked to a naked guy sporting a hard cock in the shower, so I had to leave in a few minutes.

This guy has since become a lot friendlier and it seems we're always at the gym the same times and have started to work out together, and now we're always in the shower together and he offers to help me wash my back. He's always hard in the shower and he says it's just something that always happens to him after a good workout.

Last time I was at the gym I let him wash my back. It went way past washing my back, but not very far. He lathered up my washcloth and washed my back. Before I could turn back around he had his soapy hands under my arms and a hold and squeezing my breasts. I felt his hard cock soapy cock pressing between my butt cheeks as he started to play with my nipples.

I don't know if it's that I'm in a dry spell, the medication I'm on, or what; but I didn't resist, it really felt good. I stood there with his cock between my ass cheeks and him literally trying to milk my breasts. This lasted a couple minutes until we heard someone else come into the locker room. We both rinsed off and got dressed. I was really embarrassed and hurriedly dressed and left.

Now I don't know what to do. I like working out and we only have one gym in town, and I'm not big on confrontation. I'm not gay, but I did enjoy what happened in the shower.

What do I do now??
