Female led relationships discussion

I don’t expect to find the answer, but I thought I’d ask the question! It breaks my heart sometimes when I see male members of the site who would do ANYTHING to serve their SO and yet their partner will not participate. At best they “put up with”, and at worst they downright refuse. Why?! Surely women just want to be loved and cherished and made to feel special on a daily basis. If their partner needs a little physical “nudge” then what could be so bad about that? I know I was reluctant, and now I’m still struggling desperately to do what is both enjoyable for the two of us… but why do some just utterly refuse?
