enjoy being young, im 32 (old c*nt)
when i was your age i thought the same as you.
you will develop, and once you do you will wish you hadnt!
enjoy your youth cause you only get it once.
as for girlfriends i wouldnt worry, sooner or later one of them will stick their claws into you and wont let go.
if your into watching sports like football, watch it while you can, cause soon youl have to be watching eastenders and emmerdale followed by one of those reality tv 'things'
all the best mate
ps. ive been single for about 5 years and i cant remember what its like to have a proper gf these days
