I'm no stranger to anal play but I've been much more consistent with it recently and extending my sessions (from 20/30 minutes to an hour multiple nights in a row).

I've also combined it with porn and chastity and recently I've started having these full body contractions that feel incredibly pleasurable. It kinda starts in my prostate and radiates throughout my body and leaves me a moaning mess lol.

I primarily use a dildo (although I have an Edge 2 from Lovense) I've been achieving this with just a dildo and laying on my side and thrusting at various rates/strengths.

Are these P-waves? Or maybe dry orgasms? They feel kinda like an orgasm and sometimes I'll produce some cum but most of the time nothing comes out.
