Prostate massager/vibrator

[Asphyxia]

Has anyone tried it to achieve and maintain erection?
Or maybe to release tight pelvic floor muscles?
From what ive read its possible to even orgasm from prostate stimulation
I also read that it can release tight muscles but i cant seem to find anything researched or scientific on any of this

Masturbation seem problamatic as the pc muscle activates involuntarily which makes things worse with peyronies, not sure if this happens with the prostate though
