Even if you are Chad, you'll get way more sex if you just have a girlfriend of two. I'd try to maximise daily sex with Staceys (given that I wouldn't get bored with the same woman which I doubt, but obviously can't know), so the plan is to get the hottest girl you can find and just lock her with you and fuck like rabbits. Just having to meet new woman and talk to them even if it's 30min then do all else is time consuming and also there is not that many Staceys of the same calibre that you would pull if you pulled only one or two. Going for quantity of women will decrease the quantity of sex.
