I heard my friend watching a video of him having sex with his ex-girlfriend.

I (20m) went to my friend Dylan’s (20m) house to pick him up to meet mutual friends at a bar . Dylan was in his room and the door was slightly cracked open . He thought he closed it but I guess he didn’t. I was waiting by the door for him and I hear him watching a video on his phone of him and his ex-girlfriend having sex . I heard a lot of the sounds from the video and his moaning. <br><br>He went on his phone the entire car ride to check out other porn videos until he was satisfied. When we got to the bar he went to the bathroom for around 10 minutes before joining us at the table. He spent the entire night checking his phone and occasionally laughing and looking at porn and cumming in his pants . <br><br>I’m confused on why he does this. Is this normal for guys to do? He’s not the only guy I know to do this but he does it the most frequently .
