Is something wrong???!!!!!!!!!!!?

Ok ,so my boyfriend and i have been dating for 2 years now. im 14 he is 13. Okay so as i said we have been dating for two years and we hug and hold hand once in while and hang out. But, we havent kissed at all! All my friends have already had their first kiss. Its not like i want to be like them but it annoys me that they keep repeating the fact that we have been dating for two years and that we should have already kissed. My boyfriend is really respectful, so are his two brothers, their mom has taught them to be like that. In fact my best friend was dating my boyfriend's twin brother but broke up with him cuz he wouldnt kiss her when they were both 12 i believe. So my point is that he is really respectful he holds my hand when i allow him and hugs me whenever i allow it as well. He is really sweet and stuff so i really dont care much about the kiss part but all my friends have got me thinking about it and wondering if there is something wrong in our relationship! Please give a comment, or advice.

Thx in advance
