To take it one step further?

Hi all,

I'm currently working with an Aneros MGX at the moment (This is my twelth session so far. Aneros has been my first anal experience) and have progressed to the point where I can feel that warm tingly energy building up in the prostate area (sometimes some pressure too) every time however the feelings collapse after several moments and it's back to square 1. My approaches so far have been maintaining the extent and frequency of contractions, increasing the frequency or just holding it for slightly longer.

I guess my question is, can you guys suggest any other techniques or ideas to take it to the next level?

Also, I don't think I've found my P spot yet, I don't seem to feel any of the described sensations associated with pressure on that point. Would this significantly affect me? And could any of you suggest a way to pinpoint the pressure point?

Thanks!
