First kiss with my boyfriend?

I am currently going out with this guy who I have been crazy about for ages (yay!) and he has told me he would like to kiss me and I would like to kiss him too but theres just always so many of our friends hanging around with us at school and its quite embarrassing since everybody is making such a big deal out of it. One of my friends thinks its ridiculous that we haven't kissed yet because we have been going out for 2 weeks (I don't really think that's long to be honest but she does) and every time she sees us she like laughs at us and calls us frigid and tries to make us kiss. I want to kiss him without everybody making a big deal out of it, help me!!!
