Wait she said she wanted kids as a means of making you think she was interested, but only wanted sex? *scratches head* I'd think that would be a good way to send a guy running away with that kind of opening. Maybe she was hoping you'd be a donor? *scratches head again*
Hookup culture has gotten increasingly gotten bigger. It is largely about instant gratification without any responsibilities one has when otherwise dating. Women like men have sex drives and plently like doing it. Hooking up is just a way to "scratch" the "itch". Of course there can be other things going on like the person who equates being desired with their self worth.
Overall partaking in such things is pretty superficial and those that do it regularly typically have little trouble with not mixing emotions in it. There additudes is largely that it's 'just' sex. Many things could be said about this but the thing to note is their way of being and thinking on the subject is obviously different than yours.
I have been proposition before, but I think this kind of thing is common for women to experience.
