Personally, I find it inappropriate for a twenty-two year old to be with a sixteen year old. When you're sixteen six years is a big age difference, never mind the legal implications that would come with any sort of sexual contact. You're still in high school, whereas he's (hopefully) an adult with adult responsibilities. To me, it's strange that an adult would want to be with someone who still has at least a year left in high school and is a minor to boot. I cannot in good conscience tell you to go for it, but if you decide to, be very careful, physically and emotionally.
