edit: incompatible = what they want is not on offer

This whole "what n count is ok, how many past partners or experiences are ok, is she giving me my best", etc., The guys who care about this, well, they're very likely to be disappointed, and if not disappointed then because of being deceived

It seems to me that such a guy will have to work to genuinely change his perspective if he is going to commit to a woman in a sexually free society (I personally think such change is unlikely, if not possible)

If the guy can't change this perspective, he is better off not committing. It's a square peg in a round hole.
