I've gotten myself SO close so many times when stimulating my prostate but when I get that close my ass begins to forcefully try and eject the toy due to me involuntarily bearing down and it ends up becoming painful or at least uncomfortable to the point that I can no longer keep fucking myself with the toy. Has anyone experienced similar and can you advise how you overcame it? Everything feels so good up until that point and I feel like I'm going to cum but then never can get past the edge.
