Not long enough or what? (semi gross warning)

I had a two hour session that really didn’t lead to much other than a weird contraction spasm thing that happens when i clench my pc muscles. But afterwards I had to take a dump and when I did, it seemed to stimulate my prostate a lot and I got what seems some people refer to the butterfly’s in the stomach or tingling but it was relatively intense. It was a really good feeling that I would like to replicate with an aneros but ive not had too much luck.

So was that proper stimulation because the shit reaches deeper/wider or am i over thinking it.
