hmm well my year advisor always says that 1 year of age difference as a teenager is like 4 years difference as an adult... i think i agree with that. it's amazing how different i am to how i was a year ago. while it's not like you stop changing as an adult, i think it settles down a lot once you become an adult...
myself, i've always gone for older guys...my current bf is 2 1/2 yrs older and he's one of the younger ones... when i was 14-15 i always went for older guys (like 20/21 yr olds, occasionally older) but now that i've gotten a bit older i think i've settled down, hence my wanting to be around guys closer to my own age
i don't think an age gap is always a bad thing, but you do have to keep in mind that there are many people who will, and also, like minai said, you're going to want different things out of life
now it's time for neighbours
in conclusion, just try and keep it legal
