Dude, Don't cut your hair bro. The issue here isn't the hair at all. He hasn't get laid yet coz' he has long hair and he magically won't get laid if he cuts it. The thing is YOU have to make the effort to meet girls if you want to get laid. A girl isn't going to come knock on your door and fuck you, unless you pay her. Find out where these parties are, go there smoke some herb and start talking to girls. You can take even simpler steps if you set goals for yourself, say, ok today i'm going to get 3 girls phone numbers/ email addresses and then do it. You'll be suprised how easily girls will ahnd out their number and email. If they say they don't have email then come back with some comment like "do you have electricity.?"

Also talking online to women is great practice. Whoever said get that double your dating book knows what he's talking about. In that book it tells you to use the C & F technique which is cocky and funny, the two work wonders together. I can tell you're a funny guy you just need to work on your confidence. It's already been said but girls love to be teased. for example if you're at a party and you see some girl wearing like nothing for a shirt, Walk up to her (she'll be thinking, this guys gonna compliment me on my shirt because i'm shallow) and say "what, can you not afford a real shirt?" Cocky and funny comments like that will keep them off guard and confused, while making them more attracted to you.

Don't go up to gilrs and give them compliments, buy them flowers and all that wussy stuff because that won't get you anywhere. Think about being a hot girl for a second, imagine how many guys advance on her in one day. All giving her some bs line, trying to be a "playa" You have to be different, girls see that you're different and not like all those other guys. I'll give you an example: I was at this party once and this hot girl was talkin to these guys and she had got her hair done and everone of these fools were complimenting it, saying shit like omg you look so hot, i love you... I walk over there, and say "nice hair (satirically) and walk away. And then one of the wussy guys did what i expected him to do, he goes "don't listen to that guy i love your hair." Long story short, i got laid that night, they did not.

Cease the day, go out and talk to girls, make the effort, download that double your dating book if you can. Good luck.
