I'M CONFUSED ON OUR RELATIONSHIP? PLEASE HELP?

3.5 years into my friends with benefits, He has started teasing me about loving him. I tell him I like him when he does this. I mean I do, I couldnt sleep with the same person for so long with out liking them to an extent. We never hang out alone except for random hook ups. We dont discuss anything outside of our bedroom time. But we text daily, 7 days a week. He sent a kissy face emoji for the 1st time last month. (It's been 3.5 years!) Should I consider about seriously thinking about if we should be official. Should I see if we can making it official to everyone or am I over thinking the situation?

Also Men, Why the teasing about me loving him and kissy faces all of a sudden?
