The fact that Josh has not moved into a ministry position, but is a professonal marathoner, tells me that he is choosing to be in the secular world. In conservative speak, this makes him a warrior (battling the evil "out there"). That requires alot of self-confidence and faith on his part, which can, if not watched, move into ego. Being Christian, also doesn't preclude talking about sex, even w/o the experience. Take a look at the book "Song of Songs" in the Bible, you will be surprised.
