Damage to my prostate?

Hi, I started massaging with aneros and then with an anal wand and after 3 weeks I was having super-Os with or without tools/toys. And then it suddenly stopped. I was a pretty rough player I would say, with hours long sessions twice a day sometimes, getting more and more pleasure with greater pressure with the wand. I thought of the pain/pleasure phenomenon as just like getting a muscle massage: it's utterly pleasureable but you have to go through the pain of pressing on tense muscles. Suddenly, after days of super-Os, I became insensitive, can barely get a response at all and can only get an erection with difficulty. My ability to get a response is not totally dead because I've had very very small orgasms (without toys) in the last week. But toys no longer give me anywhere near the pleasure I was having and having an orgasm is rare and nothing like it was before. What's going on? Is prostate damage permanent? There was soreness many times and some lubes burned a bit and others didn't, but I never had any kind of pain that I would associate with injuring or damaging something. Anyone able to advise me on this? I'm going to my urologist next week and maybe see a proctologist.
