Chun-li was the best originally, but Ken's (Ryu in Marvel vs. Capcom) new stuff is just the best.Now about your prob... I'm STILL a virgin at 18, and I didn't kiss someone till I was 16 (almost 17). My advice to you is to change a little. Like next time a cute girl is bagging your groceries, ask if she's seen [insert comedy movie currently in theaters] yet. If she says yes, ask how it was, and then ask if she want to get something to eat when she gets off work (and offer to pick her up). If she hasn't seen the movie, invite her to go with you later after work.
I know it sounds weird and totally NOT you style, but just have fun with it and don't be afraid of rejection... just be confident and smile if you can! Oh, and make sure you aren't buying athletes foot powder or something...
YES! IT SOUNDS CRAZY! But just do it! My guess is that your suffering from a minor self-asteem problem, and this is a great way to build it! Even if you get rejected, you'll know that you can gather your balls when nessisary!
Any, chicks pick-up on confidence, and the more you have the better off you are!
Now, if all your looking for is tail and not a relationship, then you need a good lesson form The Proffessor, Tom Leykis! Go here for a proven meathod of getting chicks... http://www.geocities.com/SouthBeach/Terrace/8181/
Just goto the Leykis 101 section and ENJOY!
