Am I going right?

Im having trouble with my aneros session. I dont know if Im doing right so I want some advices. Sorry for my english since Im not from english speaking country.

Anyways perhaps like other guys in this forum I stuck my mgx in my ass with plenty of lubes first. Then stay relaxed until I get comfortable with my toy. After that I squeeze my pc muscle at up to 70% of my limit with concentration. The concentration on the toy and the prostate. I maintain the squeeze until I shiver. I feel some.. some kind of wave like Im burning and thats all. Thats it. Nothing happens after that.

I also tried the do nothing method. Sometimes I feel the same feeling like I mentioned before. But most of the time I feel nothing. Well umm the forums in my country they say dont have any expectation for reaching any orgasms so I struggle really hard not to expect good feelings.

The question is I dont know if Im following the right path. And want to know whether guys who reached dry orgasm state had same trouble like Im struggling now or not. Thx for reading.

p.s Weed sounds interesting but its illegal at here.
