Skittlepimp is right. (Great name btw

If a girl is uncomfortable holding your hand, don't expect her to be comfortable kissing you.
Just some tips - throw in some kino, neg her a little bit, and master cat-string theory.
Going in for the kiss straight out is risky. If you aren't doing compliance tests throughout the sarge, it's like playing the stock market blind.
Here is Mystery's Kiss Gambit:
Ask her "Do you want to kiss me?"
If she says:
Yes - Kiss her
Maybe - say "Let's find out" - kiss her.
I don't know - say "Let's find out" - kiss her.
Not here - say "I understand" wait 10 min, isolate her in different location, kiss her.
No - say " I didn't say you could...It just looked like you had something on your mind..." Then go off into another routine, DHV, Freeze her out, do a compliance test, and try again.
