I think my boyfriend is a sex addict and a liar

My B/F is overboard with sex , as in nightly 3xs at times a night ! Always looking for quickies and a bit of a sweet talker . Anyway I know an X of his that said his sex issue was to much for her and he tells me he was never so aroused it's something about me and he never loved like he loves me btw he is 46 im 43 and this ex is 33 . Idk wth to think even she said what's he think he's a teenager or just associates sex as love ? I been feelin the same should I say see yah he's just a minipulater and tells woman the same ish to try and make "us" all think we are soo special ? Hmm
