help im 14 and a girl, GIRLS ONLY!?

hi, im 14 and im on holiday atm. iv recently been talking to my boyfriend of 1 month, and he said in a jokey way that he wanted to shag me. i joined in but it became serious. i told him that i wanted to wait until atleast after christmas, because, in actual fact, we might not even be together then, and he said ofcourse, and i love him even more for respecting me like that. but i also said id do simpler things to start off with, and he said hed poke me and id give him a sooky and a hand job. its not that i dont want to , cause i do, i just dont no how to, and how do i give him a good sooky? how will he poke me? also i masturbate quite alot thinking about it, and he says he wanks over me alot, but i want this to be real, and i know im ready for it! also, i have braces, will this affect a sooky? and im scared that if he licks me he wont like the taste? if anyone can help then please please please comment, cause were goin campin next week and thats when am givin him the sooky. im really grateful, thanks :) xxxx
