My experience is that age is only an issue if you make it one. Your mentality, maturity level, and communication with your partner are much more important than an age disparity. I'm 18 and have been into guys 3x my age [who have also been into me] and there is no issue.
There are obviously more challenges with intergenerational relationships compared to same-age ones but if both parties are on the same page, there is no reason you can't have success together.
Another big key is to not listen to what others might have to say. The sad truth is that most people are very repressed and judgmental when it comes to age differences in relationships. Just trust your own self and what's in your head and heart. Pay little attention to the idiots on the outside who have no clue how great an older-younger relationship can be.
(For the record, 22-38 is not really that big of a difference.)
