Everyone is giving you the optimistic, fairy land answers. This is the real answer, at first you might not mind it but once it becomes serious, people will take the piss out of it, it'll hurt both of your confidence, he'll be made out to feel like he's under your control and you'll be told your dating a little kid. People will probably say stuff like, does he need a ladder to kiss you. Do you have to sit down to kiss him..etc.
Also, once you're serious, tm. You'll realise you want more masculinity from your boyfriend, which wouldn't really work out, end of the day, the guy always likes to feel like the bigger person and the girl always wants to feel protected and small.
