Why does this guy keep sending me pictures of other girls?

Anonymous
I have been chatting with this guy for a few weeks now. We are new friends. Friendship is the only thing I’ve ever offered him because I don’t find him attractive. He is in every way not my type. I also plan to work things out with my ex when I finish working on myself. I have made this friend aware of that and he claims he plans to do the same with his ex. He claims I’m not his type all while asking me about the color of my bra and panties. All while telling me sexual things he would do to me. He proclaims his love for his ex (he cheated on her with lots of women) but will send me pics of girls he either has had sex with or claims to want to have sex with. I tell him not to send me pics so when he sends me pics of girls I send him pics of guys. then he accuses me of being jealous but I’m really not I don’t care I just don’t want a bunch of pictures of girls on my phone. I’m already running low on space as it is. I have made it very clear I don’t like him as anything more than a friend and I don’t. Yet he insist on continuing to behave like a child and I’m honestly getting tired of it. I’m considering ending our friendship. Am I behaving too irrationally?
