If you really want the title for a guy, your best bet is to hold off sex. However, if you’ve already opened pandora’s box, you have to keep him interested. You have to always bring your A game in the bedroom. It’s superficial, but a man’s sex life is very important and if you’re good at what you do, he will lock you down to ensure that he doesn’t have to share you. You don’t have to play all your cards early on, but you have to show him that your committed to pleasing him.
Try bringing a toy, a new position and if you’re not the controlling kind–take control. If he sees that sex with you gets better each time, he sees your sex as a good investment.
