You can do that without going all out. And women started the "money spent = sex given" concept.I know this is a foreign concept but you should really go out on a date to have fun & enjoy yourself with the company of a woman, not to impress a woman. If it doesn't work out long term, you've lost nothing.
Too many men treating dating as if they're paying for a prostitute or a tit for that thing (ie: I pay for dinner and entertainment, you give me sex) when you should just enjoy the company and getting to know a woman you're attracted to.
