PLEASE HELP 😽

So a few months ago I was really into this guy. We liked each-other at the same time for awhile but nothing happened. We’ve always been really open with each other about masturbation and sex with others or one another. Every once and awhile he’ll text me and have good conversations but he only does it when he’s masturbating that’s the only time he texts me. Should I be alarmed? I don’t really know how to feel about that? And he always asks me to masturbate with him or talk to him while he’s doing it...what should I do? Continue or?? It’s just confusing you know? Also when I liked him I sent teasers but he didn’t save them. Idk if that helps lol :)
