I'm just barely holding the fort at NW2, headed towards 2.5, and losing ground slowly.
I had my first kiss (and everything else) with a girl 4 months ago - at 24 years old. She is engaged and I was her affair (rather long and ridiculous story, bottom line she is getting married to someone she is unhappy with due to peer pressure, so she wanted one last 'fling').
The reason my hair didn't stop me was because I knew it wouldn't last long and she wasn't going to be mine for the long run anyway, so I didn't care (and a NW2 is still good enough for most women).
But starting a relationship is a different thing, you're in it for the long haul, and I can't guarantee that I will still have the same amount of hair in even 6 months, let alone 2 years.
What this experience has taught me about women is that they have no problems being totally immoral if they can justify it with their own emotions and will go very far for you as long as they find you attractive and especially if they are crazy about you.
I also didn't really do anything special to attract her, absolutely no 'game', 'PUA', or any other sh*t ( I don't even know anything about that ). I was just being myself and we were both receptive to each other's advances. If someone finds you attractive it's pretty hard to do wrong. If not, it doesn't matter what you do. Looks are the first test your have to pass and if you fail you don't get a second one.
