This was kind of hard to title so please bear with me. In my residence hall, we have a public bathroom. (Three toilets, three showers, you know the deal.) Every night when I go to take a shower, there's always the same guy in the last shower stall. I and my friends have taken notice that he's in there for long periods of time, and can sometimes be heard talking real deeply. While showering tonight I noticed some small and not so small moans or grunts, especially noticeable when no one else is in the bathroom. So I'm almost positive he's masturbating. While I will sometimes masturbate in the shower myself, I don't do it so often anymore. But now that I'm sure of what this guy is doing, I want to try and connect with him somehow. But, I don't really know what to do. Should I go into the stall next to him next time? Should I let out little moans as well so he can hear? Should I try and do anything at all? What are some tips to find other guys to masturbate with, or talk about masturbation with?
