Lack of orgasm/physical sensation on penis due to pressure injury

[zerocool1]

Hi,

I'm a 34 y/o male who is an above-knee amputee. I've been an amputee due to trauma, and not any disease. I've been wearing a socket that has put pressure on my groin, pc muscle and buttocks bone ( all on my right side) since 2007.

Over the years, I feel like I have lost sensation on my penis and the orgasm sensations. For the past 3 weeks, I have tried not to sit so much to recover any feeling back. Currently, I see some improvement in orgasm, however, when I have  an orgasm I feel the sensation right as it starts, but then the sensation goes away (numb) once the contractions for sperm release occur. Physical sensations on the sides of the penis are minimal when touched, other areas are so-so; the head seems normally sensitive, so do testicles.

Also, every time I urinate, the stream flow feels impeded, so does my sperm during ejaculation; it doesn't shoot like it did years ago. Another symptom to note is that if I hold back an orgasm with my pc muscle(I think its called this muscle/organ) instead of releasing the orgasm, it feels as if the pc muscle forcefully pushes upward and the flow seems more impeded without any feeling at all. So if I ever hold back an orgasm, even just once, it will cost me any little sensation I could get. Its almost as if the prostate, pc muscle and/or other organs are malfunctioning or misplaced due to the pressure; I dont know. I noticed the pc muscle area, when i touch it, has sunken in more during the years (i.e. more in towards my insides).

Given the limitations of the internet, without a physical exam, I would like any theories and possible solutions.  Any safe test you could recommend to ascertain any issues?

History:

*Low-Testosterone but wake up with erections, have occasional mid-day erections (mostly low-quality), and erections before sleep. Best erections are in the morning.
*Low vitamin D, but take supplements and I think this has been helping with erections
* I have occasional hyperthyroidism. Doctors think it's not officially hyperthyroidism, but only inflammation of it.
* Pressure near penis area as mentioned above.
