There's always the issue of where the relationship is going. Dealing with her friends and family, her habits, spending quality time together, being obligated to do things together. Not that there's anything wrong with that if you want that. But if you just want to get laid, everything else make that free sex very expensive. Let's face it.
Sexual attraction has a lot to do with looks.
Some men are genetically blessed and some aren't. You're height isn't something you can do something about. But there is something else that turn women on and that's money. Women will marry you for your money. The bottom line is, if you want to get laid it's easier to come up with a few hundred bucks that to grow a foot taller.
