Sex
It is good for a man not to touch a woman.
- I Corinthians 7:1

For there are some eunuchs which were so born from their mother's womb; and there are some eunuchs which were made eunuchs of men; and there be eunuchs which have made themselves eunuchs for the kingdom of heavens sake. He that is able to receive it.
-Matthew 19:12 (JC speaking)
