"it always seems to me like a give off an unfriendly, don't talk to me attitude around people and that needs to change."
It's funny you should mention it, I have the same feeling about myself. If me and my friends stand beside each other, and a person wants to talk to one of us, the person NEVER approaches me, but chooses one of my friends. It can bum me out from time to time, but I'm starting to not give a fuck about it.
The random person doesn't know me, so I can't blame him for approaching my friend instead of me!
Besides, it kind of gives me the silent bad-ass look, which I love. That's much better for seduction than being the guy who most people wants to talk to. They're probably approaching your friend, and not you, because he looks friendly, and non-threatening. BEING NON-THREATENING IS NOT A GOOD THING, because it means you're not sending a sexual, seductive vibe!
The only thing it helps, is it makes opening girls easier, because they will open you. But then what? They don't look at you as a sexual being, they look at you as a friendly, nice-to-talk-to guy, so you're gonna have a hard time getting laid, or even getting a kiss.
A GREAT example of this:
I was having a party, and I made a bet with my friend to see who could kiss this HB7 first. A few minutes went by, and SHE started talking to him, because he's got that "everybody wants to talk to him"-quality. A little while sooner, they kissed. Okay, I accept that. BUT!
20 minutes after they kissed, I KISSED HER TOO! It was hilarious. The thing is, there was a really non-sexual vibe going on with her and my friend. But with me on the other hand. Well I had made deep eye-contact with her all night, and being very sexual and seductive, while I hadn't said more than 5 words to her. At some point, she sits next to me, and I just grab her hand (at this point I was alone with her and her 2 girl friends, my friends was all out smoking), and a minute after hand-caressing, I just lean in and kiss her. LMAO! You should've seen the look on her face afterwards, it was like "WHAT? HOW DID HE MAKE ME DO THAT??".
The lesson is, my friend has no sexual vibe, and is therefor easy to talk to. I have a strong sexual vibe, so I just skip the talking.
So to sum up: Fuck it if people aren't jumping on you to start a conversation. They can be entertained by other guys. You're just here to bite their lips and grab their ass after they're done talking to mr. nice-talkative-guy
BTW I hope you understand what I'm saying here, the post got kinda long.
