People do what works. Kids and women alike. I had a girlfriend try that once. You're going to think I'm lying, but for real I told her "just for that we're not having sex for a month." At the time I said it I wasn't thinking of stopping her from doing that, but just turning the tables to see how she liked it. Eventually she broke down and cried and told me I wasn't normal because I didn't give a fuck if she withheld sex.
