Um we guys don't think like that... the whole winning her over too easily emotionally bit. Winning over too easily physically will make him respect you less and treat you like a bed mat. So, don't do that too soon, but don't wait forever either because then he'd get bored. To keep him interested is keep dolling up, seeing him, being sweet and interested and interesting. Give him space too. Don't flip if he doesn't text/call you back. Don't grill him about what he's done or where or who with. Don't be clingy/needy. Be pleasant to be around and you should have nothing to worry about.
