my first girlfriend was type 1 diabetic... this was way way before i was diagnosed with type 1, i was 15... (24 now, diagnosed at 22).
It didn't bother me in the slightest!! I remember her telling me before we started going out in a letter (how sweet lol) and i could see from what she'd written that it was hard for her to tell me.
Anyway... dont worry, you will find someone who it doesn't bother them... and they will be the person who's worth it. At the end of the day, i know this sounds REALLY boring... but you're only 16... still very young, are you going to college? you will find that people in college after school mature very quickly, and you'll meet new people, you'll be suprised!
It's very cliché, but if you stop looking for a boyfriend... someone will turn up, and who ever that is will most likely be the one chasing you, at which point, they wont mind about you being diabetic because if they like you enough... it wont bother them!
