I found this on a Taoist site. You can substitute partner or whatever for woman. The penis has 5 virtues. 1. The penis is Kind. It exists mainly as a tool for servicing the woman, and in this it keeps on giving and giving. 2. The penis is Righteous. It is not selfish. It performs its duty, yet it is empty on the inside, a hollow tube, with nothing of its own. 3. The penis is Courteous. It is polite. It advances or retreats at the right time. It is hard or soft at the right time. It is shaped neither squarely, nor is it pointed or sharp edged. It will neither hurt nor show lack of discipline. 4. The penis is Wise. It knows how to find a way to please the woman, and it will do whatever is in its power to satisfy her. 5. The penis is Honest. It will keep labouring until it completes its duty. If it cannot fulfill its duty it gives up completely. It is completely honest. If it likes you it stands up straight. If it does not it becomes indifferent.
