Do they really mean “only female half” will touch or enjoy female invitee?

I am invited from some couples. Before though male half join together, it was fine cause he was really appealing me.

This time, when male half never attracts me while I really want to feel female half.. and they say “lady half want to explore another woman..”

Do you think the boundary of no male half is really firm?

I really hate doing things that can be labor only to not spoil the mood.

Asking this cause I as solo female player, often feel too many couples use female half as bait to lure other women first. This : female pretend to like me while their real purpose is making men enjoy their own desire of fucking other women.
