One of the reasons that the Higher Power, as I choose to believe, is Female, is because of the devious feminine sense of humor She has to have given women not only the only sexual organ that serves no other purpose other than to provide a woman with pleasure (the clitoris), but to also provide her with the G-spot and A-spot, both of which are located inside the vagina to provide her with additional pleasure, but then gives man an additional pleasure point which She stuck up his ass! Ain't that the shits!
The prostate can be a source of great pleasure for a man if his lover learns how to massage it directly, such as with a finger (especially intense while sucking his dick), a vibrator, dildo or strap-on or by massaging it externally via the perineum. Of course, the man has to be willing to accept this form of stimulation, which many short-change themselves of due to an irrational fear that to enjoy their bodies to the fullest in this manner would in some way make them 'gay'.
An added benefit for many couples is the triple pleasure using a strap-on provides the female mate as:
first, she has the satisfaction of giving her man additional pleasure,
second, she experiences that rush of power being in control as the 'fucker' and enjoys the surrender of her mate to her as the 'fuckee', and
third, the stimulation she receives from the strap-on rubbing and bumping against her clitoris can turn the experience into an extremely bonding, mutually orgasmic intimacy for both.
Great addition to your other threads, IL!
