Did this on a whim really, was taking pics of my penis and got really turned on, had a headache to so thought it wouldnt go anywhere. Watching some aneros porn i found myself again having a really strong series of prostate orgasms and a number of anal ones as well! this was using the tempo whislt lying on my front with a pillow underneath me.
Also i found that this session required a little light contraction hold to get the muscles and prostate pulsing, which when it did i would release the contraction and let it orgasm, then repeat.
I changed to the helix classic and once again got the same, many more anal electric filling my ass feelings as well. Lovely. Still feel its stops short of being satisfied though.
