So here is my profile:

I am 5'5.5". (Checked with doctor about 6 months ago). I am pretty skinny, not skin and bones, and I am a bit self-consious about my weight even though I have never had a complaint from a girl about my weight. Not able to grow a beard (yet). I have a "young look", as in face hasn't fully lost it's baby fat coupled with being short and a mild case of rosacea. I dress to impress: typical attire is dress pants (rolled up to knees on a hot day), a dress shirt, and sometimes a vest.

Not muscular, not cut, and I'm 17.

What can I do?

As for game, I have a few questions as well.

Where does the logic apply in not acting interested? If you approach a girl, doesn't that imply that you are interested?

Should I test numbers in front of girls?

Should I be in and then out within a few minutes? If so, how would I have time to push/pull?

Thanks for all the answers.
