u way 2 young to be so scard about it! take it easy. you like him? go for it! but play hard so he don't think u easy like the other girls, make him see u as special, funny, but caring. play eye contact with him! be funny and at ease but look at him like :' you know what i want... kiss me...' but don't i repit DO NOT ask for it. think that he is a friend you ll get to know better, the rest live it to destiny... i have a bf of my own im a bit older (19) but i still make him see im not just another girl, and that he can lose me so he plays harder and remembers that a girl deserves to be treated lika a queen. then i make him feel like a king... never no, never yes. never to easy nor to hard. you ll get it from your inside how to be a 'FEMME FATALLE'
Your 13 sweetie! You dont have to have a serious relationship. there is plenty of time for that. If you really like this guy then go for it. Dont be worried about what other people think of you, aslong as your happy then thats all that matters, but if you feel in your heart that you are not ready for a boyfriend then there is no shame in that either
