Does he just want me for a friends with benefits thing ?

He texted me today after I told him how I feel for him he said this doesn't change anything between us he was reallyy nice about it then he was like I want to go jack off because we were talking about porn. We texted for hours I thinkmi came arcoss as weird or something because I said brb and he never texted back . I don't think he wants friends with benefits as I am writing this but I am just wondering is our friendship over ? Be honest ?
