Update on weird senior

So yesterday was me and my boyfriend’s 6 month, and I got to see him today :3 and he saw my blog complaining about the senior kid, and just told me to block him. Ngl I was nervous because the one kid is in my class so I feel like he’d then start talking to me in class and asking a bunch of questions, then I remembered this guy is like notorious for sending dick pics to girls so I figure an uncomfortable talk is much much much better than getting an unsolicited dick pic, especially if it can be avoided. So I blocked him, I am slightly nervous for weight training class though, I really hope he does not talk to me, he never speaks to me in person so I’m hoping he’ll just blow it off and not speak to me like normal. Or maybe I’ll get lucky and my hours will switch so I don’t have weights class 6th hour. I dunno but he makes me uncomfortable, especially knowing he sends a lot of stuff to a bunch of girls. Which brings me to the question, why do guys send dick pics? Like I get it if y’all are dating and it’s fine with the other person. But why send it to a stranger?? It’s like you’re asking to be called a creep and get blocked. What makes people think it’s a good idea?!?
