Some girls just like the bad boy or those they think are great in bed or can provide a lavish lifestyle etc. Generally those are the ones to stay away from, a decent girl who is into you won't be interested in if you treat her mean and keep her keen, or are fabulous in bed.. Her interest in you alone means games like this aren't needed. Sex will be something you learn together, and get better over time. Being great in bed, or having a huge wang isn’t what decent girls are looking for. trust me..
Insecurity for woman is a major problem however, some are better with it then others but you need to just get out there and find someone who likes you for you. And you will. But don’t be surprised that once you find a girl a lot of effort to keep her is required, even if she is a pure heart of gold lass. They need to feel secure, and this is more important to them then how you look or how much you earn or how big your pecker is..!!
