Men tend to think with their dicks and that is bad. Woman use their sexuality to get what they want (dinner, drinks, money, marriage, etc..). Men are foolish to think they are in control... it's completely the other way around. Women control men. Most men cannot think properly because their libido controls them.
Young men are not able to realize this until they hit their mid/late 30's. By that time they will have dated many women, paid for many dinners, movies, drinks, gifts, etc... You will have spent thousands of dollars, perhaps tens of thousands -ouch.
Just lay them and leave them. Don't spend lots of money on them, don't marry them and don't have kids with them. You'll be much happier, richer and most importantly... you will have all the freedom to do whatever you want and go wherever you want in your life.
