A weird technique with puzzling results

So ive posted about this technique some time ago, i havnt actually tried it for about 2 years because this seems like a very forceful method.

For me, bizarrley it works 100% of the time, even if i am not totally aroused. So it needs to be the Eupho classic model and I pull my legs back like a baby might do i.e. I bring them up to my chest, then I play with my nipples to get an erection. Its a bit of a strain on the back and legs, i would even say my legs are tensed a little.

Within 20 seconds or so I get an orgasm. It lasts as long as the erection does and usually its very pleasant indeed, in fact its probably the best orgasm through the aneros ive yet to experience. It's just hard to have more than 4 or so before it becomes too tiring.

Oddly no other device produces the same results as the Eupho using this method.

After after I change position (lying on my front) i get wonderful feelings! even one today that felt like a different kind of mini orgasm, a sort of hint of whats 'possibly to come' type feeling.

However if i use the device 'properly' i.e. on my back, relaxing, focusing and so on, it does nothing whatsoever for me, no feeling at all. This is why i prefer to use the helix/mgx/maximus or progasm as these generally work ok in this position, but not as intense as the Eupho when adopting the forceful method.

I wonder why this is the case? it must have something to do with prostate position in some people.... or something.
