My friend keeps peeking at me

We were close friends …

So My friend and I, like always, had gone out to talk and do our usual things, but unfortunately we couldn’t find a restroom the whole day. After we had dinner, we were forced to go somewhere and pee together. When my friend finished, surprisingly he came and stood next to me, put his hand on my shoulder, and while I was peeing, he looked at my dick. I got upset because he was looking without my permission.

Some time passed after that incident, and several times I noticed that in the gym locker room and at the pool he keeps trying to see my private parts (when I’m showering, he secretly looks at me through the crack in the door). This has really annoyed me. (I don’t have a problem if he wants to see—he should just tell me directly and I’ll show him, and I told him this—but he keeps doing it anyway.)

Once in the steam sauna, my shorts loosened, and he leaned in and stared at my private area
