So I [M30] have been dabbling with prostate play for years now and it always goes the same way which is not ideal and I've love some input...

For context, I'm a fit 30 y/o M with a clean diet AND also consume fiber fairly frequently.

So when I want to play I'll make sure I've had a "movement" a few hours before, I will then use my favorite toy which is a hard curved g-spot vibrator. I can usually prop it up so I ride it. It feels amazing and I start dripping within 30 seconds. I then feel a bigger sensation building and around the 2 minute mark I'll feel the same feeling as if I'm having a bowel movement, and I push through it, but then I'll pause to see what's going on and remove the toy then sure enough it's covered and I'll have to stop and clean it off. Then I'll go back at it and the same thing seems to happen, but often it will trigger having a bowel movement. So then I'll take an even longer break to use the restroom. This gets annoying and messy. After 2-3 of these cycles I can ride and play fairly cleanly, but at that point it's been 15-20 minutes and I'm either sore or lost interest.

The toy is only about 4-5 inches, it hits the right spot and makes me drip so I know it's good. My partner wants to play with me as well and I'm interested but since this always happens I'm sure the result would be the same and that would certainly kill the mood. I got an anal enema and tried it once but felt very unnatural and a little scary ( I only did half the bottle) and since then I've not tried it again.

What's the solution for this? If I don't eat all day will that ensure clean P-play?
