Aneros and not being able to let go due to anal fissure and filling bladder

Hi,

I've been using the Aneros Helix Syn off and on for over a year now. It gives me very good feelings in many ways and I can have a very strong traditional penile orgasm with it still inside that leaves me in sort of a... clouded state afterwards. I feel good, real good. Like from having great sex with a woman you love, kind of. Or more, hard to describe. Either way, the aneros brings me great pleasure and enjoyment.

However, I have not experienced what I would call a prostate orgasm or anal orgasm or anything like that. I always have to use penis stimulation to achieve any kind of peaks of arousal that leads to orgasm. And when you do that... you empty your fluids and you lose all your horniness and can't keep going. Still, it feels great though.

I'm thinking that part of the reason I can't fully enjoy the sensations and reach orgasms is due to that I cannot relax completely. Why? Because I have an anal fissure which I've had for many years. 10+ years in fact, the doctors say the best method for me to get rid of it is to relax my asshole using dilation and such (essentially using buttplugs). So I figure using the aneros won't hurt either. I have undergone anal dilation therapy now for 3+ months without much improvement, but apparently it can take years to fully heal.

For those not in the know, anal fissures and other anal wounds and hemmorrhoids etc, will often force the sphincter muscles shut and cause muscle spasms in the area, especially during stimulation or using the muscles in any way (even peeing will cause muscle spasms for me). This is probably helping me achieve a lot of pleasure very quickly, but also why I can't fully relax and enjoy the built up tension.

Another thing I've noticed is that I seem to be shutting off valves inside of me somehow... Let me explain. When I masturbate with the aneros or without, I rarely have any precum at all - just completely dry. Instead I feel an increased pressure build-up inside and if I go pee that pressure is relieved.
I can start masturbate manually or using the aneros directly after having emptied my bladder and still get this result within a few minutes. Letting go also feels like I'm just gonna pee myself. Sitting on the toilet I tested this theory and noticed I was basically peeing constantly, sometimes a few seconds inbetween the drops (not a constant stream), but just endless pee... In the end I decided, this cannot be pee. It was clear liquid and seemed to only appear in such quantity and speed during masturbation. Am I redirecting my precum into my bladder? Have I managed to increase my precum production a lot from the prostate stimulation and just not having any place for the liquid to go rather than into my bladder due to "valves" being shut off due to tight muscles?

I don't know. This whole thing is making me very confused. I don't think anyone can really help but I'm reaching out to see if anyone has had similar experiences in any way with anal fissures, tight muscles, uncontrollable spasms when peeing/taking a dump, seemingly filling bladder from prostate stimulation?

Thanks for taking the time to read my long and rambling post. I appreciate it. 🙂
