A closet gay...being homophobic as his superficial facade
Might also explain his tendency to laugh at her underwear and tell her he smelled. If he was a closet gay he might feel considerable distaste/ ambivalence/ difficulty knowing how to relate to the naked or semi-naked female form and all the associated feels, sights and smells.
Part of what's repulsive - for me - is his complete lack of authenticity.
His manner and expressions seem plastic, acted, contrived.
I suspect he has no real Self.
Something went really wrong somewhere :facepalm:
