Sorry for the late reply! Yes, now I get what you mean. Thanks for examples!
We have a way of dealing with this in game through dialogue. The Mistress asks the player if they, for example, enjoy something or if they find it embarassing. If they find it embarassing, then the dialogue mocks them and points out how embarassing what they are doing is. I think this same approach could work for the straight or bi-curious person who would like to be forced into interacting with a man. I'll make sure we incorporate this when we get to those scenes!
