Oh, you'll be fine.
Some of these people are gonna be smart asses. Others are gonna give you some crap typical answer.
You'll be just fine at it...my tips would be:
- Keep your lips soft, don't crush them in. Trust me...me and my girlfriend BOTH had experiences like that with our exes...and it is not pretty.
- Don't shove your tongue down his throat too early. Give it time and you'll know when.
- Don't focus on what the Di's and donut's are. Don't sit there thinking: "Oh man, the people from yahoo answers told me to do this! I better be careful!" Just focus on the kiss.

Don't worry, you'll do fine.
