If it's legal where they are for a 22 year old to have sex with a 17 year old, it's OK IMHO as long as they are compatible. I had an 18 year old girlfriend when I was 22, and although there was a difference in maturity between us, it was not that big and we got along well.
4 years would be nothing at any other ages, but a 17 year old and a 22 year old are in completely different stages of life. I think it's questionable at best.

She 17 what is she doing with him, it would have been better if she were older say 19-20 and he's 22 or older.
