When I am using my Aneros, I lie down on my stomach to relax. I feel this is the best position for relaxing and enjoying the prostate sensations for me. Other positions such laying on my back/lying sideways don’t work for me. However, whenever the involuntary contractions begin, my penis starts to get stimulated due to being rubbed between the bed and my nether region. Due to this, my penis starts to take over my prostate and I eventually ejaculate(Super-T) within a few minutes. Due to this, I have never been able to enjoy mini-Os and super-Os of my prostate.
How can I prevent penile stimulation when lying prone with my aneros?
