Nationally, men spend an average of $80 on a first date. But in this study, guys who spent thrice as much ($240 or more) increased their chances of being in a serious relationship by 34 percent. And guys who spent below $80 were more likely to be sexually promiscuous than the ones who decided to pay a little extra.

So below $80 appears to increase your chances of getting laid.

I enjoy being treated like the queen I think I am. But if some guy was shelling out close to $300 on me for our first date, I would think that he was just trying to be a show off and values money over love. My love don't cost a thing! Yet on the other end, if a dude isn't willing to wine and dine me properly, I'd think he was a cheap muhfucca and might skimp on other places in the relationship...like the bedroom. NO. THANK YOU.

Some sort of mental gymnastics there about how she isn't whore.
