It’ll always be better when the “lust” is reciprical, but a man can still be physically attracted to a woman, regardless for her feelings for him. Not sure why that is surprising to you.
No, not really meaning a sex partner who deep down isn’t that into you but fakes it or at least is willingly having sex. I have always been astounded that some men enjoy sex with the truly unwilling. Like a scared child or other rape victim. Maybe these guys who angrily demand sex from some chick who accepted the drinks are halfway there, wanting sex with someone who doesn’t want them and is angry with them.
