Kissing is possible just don't be too embarrassed to try. Use what abilities you do have the best way you can. The teen years can be a hard period. It was hard for me. Come to terms with it and with your place in the world.
Life is a constant learning process.
There is no such thing as failure, only feedback. There were times during my teens when I thought I was the only person in the world like this, and I was just being punished. Well, I have been there and have gone through it, and I am 10 times better for it. I am nowhere nearly as shy as I used to be. Enjoy your teens.
