Polyamory

met a really seemingly wonderful guy said he was into polyamory and wanted to attend hai workshops to hip me to intimacy-love-sex etc., so fine i agreed however now he seems to have no interest...as i am not his 'body type' yet he wants to get married and wants me to be his 'partner'..i find the whole thing rather fraudulent in both agenda and emotionally i think he has had other problems in the past...any thoughts? It seems as though i am the one who is inadequate for him...i perform orally and he is happy with that yet has no interest in actual consummation of this relationship? Any thoughts out there?
