Best practices for cumming with sounds inserted

So far I've cum with sounds inserted without any negative effects. They have been everything from improvised straight sounds that were really just sterilized metal objects like stainless steel chopsticks or the non-business end crotchet hooks. With proper sounds I've cum with Van Buren and Pratt varieties inserted fully. I've been able to either cum around the sound or release the geyser by slowly removing the sound slowly. As long as I don't leave a sound in while cumming hard, I feel like I'm avoiding the risk of affecting the function of the various sphincters in my urethra. I love the deep insertions and flicking around such sounds. I also have Hegar and Rosebud sounds that I will likely cum with inserted. The force of an orgasm forces the sound out sometimes, but other times I must guide it. I'd appreciate any advice or experiences that others have had.

I was into wearing Foley Catheters a week at a time. When sexual pressures arose, 2-3 x a week I'd masturbate with the catheter in place, with a considerable amount of semen flowing around the catheter out the penis. I would pull firmly on the tube to seat the balloon against the opening of the bladder to reduce retrograde passage of semen into the bladder. Of course I never knew how much actually passed into the bladder. It didn't really matter. I never got an infection. I never noticed any effect of catheterization on the sphincter function after I removed the catheter--even after had ejaculations with the Foley in place.

I have had many orgasms as the sound was being withdrawn. Feels incredible.

Never tried sounds, looks like too much work and prep, and clean up, also risk of damage or infection. But to each their own, play safe and enjoy.

I too have come with sounds inserted. Never had a problem with infections and just had to be careful not to use too much pressure otherwise I might be sore afterwards.
