Interestings. Sounds like Finalgon is quite a bit more intense.....and longer lasting. I wonder if it's the synthetic nature of the capsaicin or the dilator?.....or both? Did the substances you mentioned stop the process? I've heard things like yogurt, Olive oil or sour cream help with capsaicin.

My experience with capsaicin was plenty intense but it did fade after about 30 minutes. I certainly wouldn't want anything longer! I'm not sure if being securely bound and gagged made it easier of more difficult to bear.

I wouldn't say absolutely, positively never again but it's certainly a fairly firmish "soft" limit.
