Realize that almost any time is a good time.
Unless a man isn't in the mood or prefers to be turned on first, the prostate is always up for action. While this erogenous zone comes alive when a male becomes sexually excited, it can also send amazing sensations sans erection and other stimulation. It is best, however, for a man to be already aroused before you go "probing," lest he's likelier to experience pain or discomfort.
