Meh, there's no secrets involved. It's simply the free market. More girls fewer SD's. I think I'm a pretty good SD, I have given away WAAAY more fucking money and gifts than I got back in sexual activity. But if you're keeping a ledger, you're doing it wrong in the first place. I like to make sure my girls grow (ie. get their shit together) and I pick girls that have something going on..school, jobs, goals. I'm not buying spare lobutains and handbags, I'm helping them get a leg up... at this point a couple of the first girls I had, we're not even sexual anymore..I tend to think of them as almost daughters... (really at my age they could be). Maybe it's because I didn't have kids but I'm actually proud of what they are accomplishing and I helped them get there just a little bit.
Anyway now I went and made it all weird.
