what is the most senstive bit of the prostate
darrenmynameis,
From some of the reading I've done on prostate massage it has been said "The center of the prostate is very sensitive, so massage only the sides of the organ." This may or may not be true for you as well.
Personally, I have not been able to detect a discernible difference in sensitivity to any particular area of my prostate. However, I must also disclose I'm an aging male who has undergone radiation therapy for prostate cancer and have lost some measure of sensitivity overall.
As you can observe from the design of each Aneros model, when inserted it is likely to massage mainly the center area of the prostate and not the outer lobe areas. If the lateral lobes were more sensitive, I'd expect the basic design would be different to take advantage of such a difference, if it existed.
I think a more important concern is the amount of pressure applied, rather than the location during massage. We need to remember our internal organs are much more fragile than our tough outer layer of skin. It is far too easy to stretch, bruise or tear the delicately intricate tissues of the uro-genital tract. A commonly noted saying is to apply no more pressure to the prostate than you would as if rubbing your eyeball. IMHO, that is a wise practice.
Good Vibes to You !
