There isn't an equivalent, that's why you can't think of one. It's men who have invented these dehumanising terms for women. Generally women don't talk about men like this - reducing them to their sexual usefulness - either.
Yes, they do, quite frequtly, and it's been a minor bugbear of mine for a long time. I see it mostly on Facebook, by younger members. Women drooling over men in kilts, hinting at what's under them. Women saying "I'd do him in a shot!" about a handsome man. A photo of David Beckham's ass, together with his arm, along with the slogan, I just love David Beckham's.... watch! hahaha! and loads of comments of women agreeing. Older women encouraging other older women to get a toyboy, or going on about their own toyboy. The very word toyboy.
Let's not pretend it doesn't happen. It may have started with Sex and the City, that idea that women can and should have sex the way men do.
I've never commented on any of this before -- I know I'd be regarded as an old prude; I don't really care, but it's not important enough for me to step in and give my opinion.
Which is, women behaving in the shallow way of men, regarding other humans simply as sexual playthings and their body parts as things to drool over, is not exactly liberating. I think we should be better than men, not descend to their level. We didn't like it when men did it to us and talked about us in this way. I personally don't like to see women do it; it grates on me. But free speech and all that. I won't ever try to correct them.
