Hi there cheech, my impression is that if you are doing better at talking to girls then it may be time to move forward by initiating touching. I am not talking about inappropriate touching, but a pat on the shoulder, a friendly hug with girls who are friends. If you are walking behind a girl you like, you could put your hands on her waist. In a more intimate situation, try gently brushing her hair away from her face. You could also learn a bit about massage and offer your services; most people would love to have a massage. Touching is generally much more flirtatious than talking and will get girls to think about you in "that way" without you having to say anything.
Also a word of advice for responding to internet dating sites. I know when I put my picture up (this was 10 years ago) I got tons of responses but most were very brief and not thought-out. Something like "hey, you can contact me if you want." Put some time and effort into writing a generic response that conveys something unique about you, what you want from a relationship, and what you bring to a relationship. Then you can just tweak it a bit for each ad you respond to. It's like developing your cover letter, and your profile is your resume. If you do this, your response will be better than most of the replies she receives and it should help your chances of being contacted.
Good luck, muchacho, it sounds like you have made some amazing progress already.
