Confidence is everything, as a woman i can say that it doesnt matter what you look like, if you can be funny without being creepy or are cultured and wise and can teach her things that are interesting she will want to keep seeing you. Not speaking is awkward. All women love a man with confidence but that doesnt mean be arrogant or an asshole or disrespectful by being foul and talking about your penis. Pity is also something we dont like. Be yourself just dont try too hard, we can easily pick up on that. If you feel unworthy then dont even try, because you will have self sabotaged yourself before you even took action. Hope this helps.
