This. I went through a dry spell, too and last month I decided, the hell with looks and got laid, literally, the very next night. I'm "shy" too, I have social phobia and I can tell you that alcohol is a helluva drug. A little apathy and humility mixed in with a cocktail or two and you'll get your two minutes of shame.
i'm shy as well, took me 21 months, almost 2 years... it'll happen, i guess there's a reason they call it "gettin lucky"
smoking weed gets you noowheree with girls. unless your smoking withh a girl. usually when im high i notice a considerable difference in my confidence, it actually drops dramatically. if anything drink a bit, 3 - 5 shots, dont get rettardedd. just keep in mind if you talk to a girl and it doesnt work out, your in the same place you were before, so why be shy? if it does work out, you get laid brotha!
