snog each others faces off every time u hang out?馃 Not kidding that's half of what we do in our time. To be honest we're both 19 and this is our first proper relationship so maybe we're just really in the lust?馃槀
Yup that's absolutely normal at 19. (I wish it were normal at 53 too but sadly my g/f thinks otherwise. Having said that I went out with a woman four years ago who snogged like we were 19, it was lush.)
So yeah, just enjoy it, enjoy being young and in lust, it won't last forever (if my life is anything to go by) so just make the most of it!
