There's always going to be SOME things that will change after you tell her how you feel about her.
I personally think it's faggish to laugh at someone for a kiss. No one's a bad kisser, everyone just has different techniques..and you would be going by your feelings when you kissed her...what's funny about it? nothing. And if she's wonderful like i'm hoping she is for you to be in love with her..then she wont laugh at you
kiss her
