For the last 3 years or so I've been experimenting with solo anal play, and recently have gotten a aneros after reading some reviews. I was also diagnosed with low testosterone 2 years ago and have been on injections for it ever since. I read online that the sensations are related to the prostate being swollen when aroused but when I feel it with my finger when aroused I can't really feel anything, I've tried the aneros and some other toys and I don't really feel much. I also read that as men age their prostate gland gets larger so does that mean I need to be older before really experiencing the height of this pleasure?
