There's something going on in that situation and not totally communicated here.
Whether the OP knows of it or not... I dunno.
I get the impression that the guy feels his masculinity is being assaulted (whether correct or not).
Repeatedly bringing up something about sexual needs... bringing in sex toys... making demands, all have the possibility of unnerving him to the point of doubting himself but not being able to communicate his feelings and thoughts...because... he's supposed to be "a man" and impervious to any of that. He's supposed to be the alpha bull in the pasture in his head.
Perhaps wind back or peel the onion all the way on this one, OP.
You may be pushing a great guy that you care about into a self fulfilling prophecy...
(or he's a selfish un-horny prick... either or)
