I have this issue whereas when I insert the aneros, I'll get an immediate reaction from my body that sends my rectal muscles into a spasm, which is very, very nice. Things seem to progress quickly in terms of swelling my prostate and when my PC muscle gets involved, my body flinches, clenching hard on the aneros, killing the subtle build-up.
My boyfriend (who is already multiorgasmic with regular super-Os) says that when this happens to him, it's impossible for him to have a successful session. He states it over stimulates the prostate too soon by having the device slam into it.
How do I stop this initial flinch which haunts progress? Would starting out with a finger be a good idea? Like, inserting but not yet touching the prostate, just to get my body used to a foreign object being inserted anally? Am I not inserting the aneros slowly enough?
Any advice would be greatly appreciated.Source: http://www.reddit.com/r/aneros/comments/3nkvgs/initial_flinch_killing_sensation/
