How to kiss a shy guy?

at previous parties we've flirted and I got quite drunk at the last one and grabbed him in the crown jewels (cringe) but he said he didn't mind. a lot of flirting went down and he said he was going to put his number in my phone but somebody else took my phone when he went to grab it (cry)
i got a bit depressed as the alcohol was wearing off and started talking about how i'm the ugly one in our year blah blah and he said he thought I was 'well fit' (so romantic:L)
we're both going to a christmas party and a new years one and i'd quite like to 'get with him' how would I hint or go about it?
we're both 15 if thats any help.

Watch the body language. When you get into another person's personal space and they feel uncomfortable, they'll step back. If that happens, you should back off too and understand he isn't ready yet. If he feels comfortable with you close to him, he's ready. Maintain constant, direct eye contact and keep getting closer and closer, then, smack! :-)

Learned to read body language on every person to handle all the necessary things to make it comfortable way.
