A bit annoying

So... I have been meeting with a guy regularly as a whole FWB (friends with benefits) and hes lots of fun likes to have me in panties and be all in charge. Butone things starting to get me, 6 out of the 10 times we've met up, he'll invite me over or plan to meet some place secluded. We start messing around which mostly involves me letting him just rub his dick between my ass, some times he'll rub on me or use this thumb and just rub circles on my hole. And after about 15-20 mins of that he tells me he's ready, I'm normally laying face down so I prop my ass up to take him... And all I feel is the tip of his dick against my hole and him jerking off till he shoots all on the outside, then and only then dose he give one push in. I asked him why once and he responded with "I like the idea of using cum as lube to fuck," I told him he could maybe get me off then use mine, which he then also explained that before we meet he'd normally been "edging" for a good hour prior so he just is soooo horny he cant help it or some crap. Hes fucked me like a normal fuck the first few times but now all I get is this... Which also has been meaning I haven't got to cum, except this most recent he at least "rubbed my ******* clit till I squirted" according to him. I dont know if im keeping him around cause I just moved and hes been my first regular hook up, and something is better then nothing or if I'm just being lazy... I wonder if he does the same thing to his wife lol.
