Hi awkwardgirl905
It's difficult to respond without a little more information.
How many years are there between you?
This may make a difference, because, after all, someone may prefer not to date girls several years younger, but might not think that one or two years actually counts.
Some boys would rather not date under-age girls.
How do you know that he doesn't date younger girls?
How do you know him?
Are you friends already?
There's a thread on age difference, and I think that the actual ages can be more important than the difference in years.
Have a look:
