Give her a Challange, like: how good kisser u are, on scale form 1-10, when she answer, no matter which number she says, Just hit her with : i dont believe u and smile
After that there is only two possible follow ups either she will say to u "u should try and evaluate yourself" or ask u about how good are u. And remember u are always 11
if she dont believe u say to her she can try ant tell
.
The next one is pretty simple: step closer in buffer zone and ask her: Tell me three reasons to not to kiss u! If she hesitate, go for it, stick your thong in her
she wont push u away.
