some nice advice but i must add my bit,what does she think of you first off,if you both get on well make each other laugh i dont see a problem with going for it,female 15 year olds are much more mature than 15 year old boys so shes probably on your level.take it easy she will be 16 soon,and as time goes on you will never notice your very small age difference.in my experience age should never matter if you belive you have met the right person for you,i met my partner 3 years ago and we have an 11 year age gap(she's older)but we love each other care for each other and look out for each other.i just wouldnt want to be without her.so good luck hope it all goes well!!
