What is it about some men where they have to use a more aggressive approach to get women?

I've met guys that have this approach and I personally am really turned off by it even if I originally thought they were REALLY attractive. That's just me though, there are guys that I've turned down so they go for my friends and are still with them for years, a year, or months later now. I think it has to do more with the women you are trying to attract and what they like. Some women like to build a friendship first, or feel like they are in control of the situation. Some just need to know that they are ually desirable. If it works for you, don't question it. :)
