This might sound kinda weird but hear me out.
A quick Google search reveals a lot of science behind why a good poop feels so satisfying.
After several preparatory steps, including a clean colon with an enema & lots of lube, I gave it a try with my Syn V.
Incredible sensation!
I actually realized in one of my first aneros sessions that the sensation of the pressure on the prostate is something I have experienced before when I have had a poop on the way, like desperately needing to poop but not being able to.
Yup! It's a regular part of my sessions now. Gently bearing down on the device usually moves me in the right direction. Also, yesterday I had a good growler on deck and got some really nice P-waves using contractions.
I havn't pooped out Aneros at least on purpose but i have done so with large objects and it feels amazing. It's not something i really talk about because people always assume only gay people do anal play which is far from the truth. But its nice to always talk with like minded people. I love how we all can talk as mature adults here even subjects such is this.
