I think the term is Heteroflexible. I would not consider having a loving relationship with another man nor would I consider myself gay or bi. But, I do show great respect for any man whom my wife chooses as her mate. That includes oral and anal if he chooses. Its respect given by the cuck to the bull by submission. Showing respect includes rubbing his feet, serving him, caring for him during copulation with my wife or sister-in-law, caring for his offspring he creates with my wife and swallowing his seed when his need arises.
