Hey Roadblkx,
Im gonna number my responses:
1. You ruled out the gym in your post, which before i got to that point would have been where i would angle you towards.
However, it seems that you arent happy in the skin you are in, work on it man, really. You MUST be confident in yourself, gym aside, i suggest you figure out a famous person who has a similar physique as you and copy their style, odds are they have had all sorts of people telling them whats best for them. Copy it but not to the point where you are not comfortable.
2. This is something that alot of us had, you got to rip that part out when you are running game. Cocky funny is the way to be. They do not have more important things to do, keep the mindset; you are making their day great, you bring fun whereever you go, they WANT you to talk to them. you can be cheeky as long as you smile! the quote you put about sitting, i bet you had a huge smile for that and rightly so!
3. Do Kino appropriate to what stage you are at;
the start is playful not sexual, then progress.
