Sounding during and right after ejaculating

I have a fetish of being stimulated right after I cum while this is usually painful to some I find it very erotic even though it can be too much. I want to know what it feels like to use a sound inside while I'm ejaculating and afterwards. I'm guessing a small one so have enough room to allow semen to flow around it.

Please do NOT use a sound while masturbating and ejaculating.

You can use a catheter because it is flexible, but if you're masturbating with a metal sound in place, you could really injure yourself.

What about extremely light masturbating not rough just tickling the head some. I'm not talking about deep sounding either just he top half of the penis.

That's OK.

I thought you wanted to sound all the way into the bladder while you masturbated with a metal sound--which is definitely NOT a good idea.

Oh No I agree deep sounding and masturbating I would never try I just want to feel the sound inside the top 1/3 of the penis from the inside that is the most sensitive part when ejaculating.

That's just the advantage that you can masturbate without sufficient erection. I am very happy about that, because at 72 years of age you have problems there sex would not be possible without a sufficient erection. But that's enough to satisfy me. This is very important for me as a habitual masturbator. Occasionally I can only masturbate after a sounding session. I now get a 12mm Hegar dilator with 19cm length past my prostate. It is very pleasant when the sound passes through the prostate. Then I can massage the prostate from the inside. I get an 18mm Hegar dilator in my Meatus Externa. I have always inserted a 18mm penis plug, with which I can also masturbate. The plug I take out only for the sake of.

I just pushed a 12 mm dilator with 19 cm length. If the dilator slips through the prostate that is very pleasant. The dilator I will now at least an hour to wide it. After that I'll masturbate nice. Sperm will come out only slightly immediately, because it is distributed in the now expanded urethra and then seeping out slowly.
