After a douche and good lube, use the perineum arm positioned underneath the scrotum and the main prostate arm to gently insert and sit firmly up against the prostate (don't use with a full bladder unless you are into golden showers) by manoeuvring with the handle and rhythmically squeezing and dilating the anus. The feelings build well and increase in intensity. By rocking the pelvic area, the prostate will be under maximum stimulation. When ejaculation is imminent (and this can be held off for hours if you so wish), cease direct stimulation of the penis and let the Nexus do the job - Man ... what an orgasm! Superb!! Now allow plenty of time to recover!!! Take a good hour or so (or even longer) with this great toy and let yourself go with it. This toy is also very easy to clean. Its an absolute must for all men to have in their toybox, an absolute pleasure for all purveyors of the anal indulgence. The Nero has been designed to stimulate the prostate gland a.k.a. the male G-Spot. Prostate massages have been used for years to intensify sexual pleasure and improve the health of the prostate gland.
