My roommate [M]asturbates in his sleep

I used to live alone; however, last month I decided to move, as the rent was too steep for me. I saw an add for a two room apartment and thought it’d be great.

I moved in and thought it was pretty neat. It’s not a two room apartment, it’s more like a one bedroom with two separate beds. The guy who I was going to share the apartment with seemed like a pretty cool guy, until night came. Every now and then during nights/bed time I would hear grunting and obvious sound of him masturbating (if you’re a guy, I am sure you know that sound). For couple of weeks I kept it to myself and didn’t really do much about it. However, as it was getting more frequent, I would show signs that I am still awake by (fake) coughing and stuff like that. Still, he didn’t stop, until… well, you know, until he was actually done (I assume).

I didn’t want to confront him either, until about a month has passed, as I am still the new guy and still saw it more of it like his house, rather than ours. This kept happening, until around last week from today, and this was when I thought have had enough and decided to confront him. While he was going at it, I decided to turn the light on. I thought he’d stop, but to my surprise he kept going. That’s when I decided to approach him to his bed. He has his eyes closed and was keep masturbating. I poked him and also called out his name (I didn’t yell). He kept going and around that time was when I knew this was getting ridiculous. I just turned off the lights and just went back to my bed.

Is it possible that my roommate is sleepwanking (masturbating in his sleep)? I mean, is that even a thing? Or is it possible that he was so into it, that he didn’t even noticed? To this day, I still haven’t confronted him, as this could be embarrassing and/or a problem that he is dealing with.

What should I do?
