The story about the freezing operation sounds horrible and perhaps something bordering on malpractice. It's another example of why it is so important to get multiple opinions before any surgery. My dad had a greedy doc who did unnecessary prostate surgery on him, as he learned from another doctor years later. Unfortunately the second doc would not testify or go on record with his statement. Still it caused my dad undue suffering. My wife had to have a hysterectomy about 15 years ago and the doc wanted to do it "old style" with a big incision and I said she should see a doctor that a woman friend had gone to who did it with a laprascope. With the second procedure, she was up and around in days, not weeks. Always be careful to get a second or even third medical opinion.
As to the real topic of this thread, I think it's not possible to feel the actual cum, but you can feel the throbbing of the guys cock while he's cumming if you both sort of lie still and stop thrusting and moving. All that other movement masks the subtle throbs. My wife and I have tried this and she can feel throbbing in my cock. Also, same thing goes for the reverse situation.
