a thing with my colleague

so this colleague is straight and committed but everytime we talk, he makes it involves something related to sex. Either he flaunts about his dick or his stamina. I have a feeling that he maybe wants to confess something but idk if it's correct ... he doesn't know this side of me yet.... but I'm just curious to know whether he is curious or not lol.... like once when we were texting I just said I'm fapping.. he texted me come let's fap together if you want to.. WELP!! is that a hint or am I being too delusional!!!
