I have used aneros for a long time, there’s been a few times where I have lingering pain in rectum and in prostate but I’ve never seen blood or anything.
I don’t really use aneros for prostate orgasms, I use it to clear out prostate fluid which often times makes my orgasms and erections stronger. In order to do this I use the aneros to press fairly firmly into the prostate on and off for maybe 3 minutes. I press a bit harder than you might press to check a pear for ripeness.
I am since having some issues, like pelvic pain and a bit of pain in penis, and less sensation.
It’s odd because usually when I do a prostate massage after a few days it increases sensation in my genitals.
Is it possible to press too hard and injure yourself?
