As someone said, it depends on what Christian denomination you ask and what individual Christian. IMO it is certainly a better option than other ways of meeting one's sexual needs, if someone is single and the needs are strong. People are marrying much later these days than they did in the past, and sexual desires are natural. I have never seen anyone with really hairy hands caused by doing it or going blind as a result! I agree that it's best to avoid doing it with pornography, though.

As far as Dr. Kellogg, I agree that he was fanatical. However, I know for a fact that at least one male relative of his had sex, because I personally knew a Kellogg family who had descended from his heritage. They went to my church. I don't blame the current Kellogg's company for their origin and don't think they should be punished. So, if I like a certain cereal from them, I buy it!
