I am experiencing a near-constant prostate tingling.
Whenever I get horny, I undress myself, jump on my bed and do pc muscl contractions to massage my prostate internally.
It feels so fucking good, I get pleasurable pulses that grow bigger and stronger, spreading throughout all of my body.
I feel like a vulnerable little girl as my body starts shaking violently and the contractions start automating. I lose control over my body and it "rapes" me until orgasm.

The orgasm itself is so fucking amazing. It has no refractory period (unless I squeeze reaaaally hard and cause a wet orgasm, which is not the goal) so I can experience multiple at the same time.
My whole body convulses as every part of me experiences that orgasmic feeling I would have had on my dick with a traditional orgasm.
It's also muuuuch more intense.
