More than just the side effects
Anyone who has ever read about the "dangers" of butt plugging or read advice and tips about using a butt plug will get some grave warnings or advice that is, at best, repeated as if it is tested and based on experience.
The grave warnings include permanently stretched anuses, which leads of course to incontinence. Now, this may possibly be a side effect, if and only if you don't use common sense. There is simply no need (other than the challenge) of getting a watermelon sized butt plug in your ass, especially if you force it in.
So, you can ignore all the grave warnings and you can ignore the tips and advice and really get into the benefits of living plugged.
I've done everything I'm likely to do in the way of activities, including going out in public, to parties, to dinner, the movies, grocery shopping with my plug in place; others talk about other activities like running, bike riding, etc. with a plug in place, and I can say that being plugged while doing whatever you do enhances that activity.
The true side effects of living plugged is the utter feeling of bliss that accompanies it. As I write this, my plug is firmly in place, the ring base is pushing against my anal opening, my sphincter is stretched open an inch, and the egg-shaped head of my plug is filling the lower part of my rectum, with just the slightest, but evident pressure on my prostate, and my cock feels that it is on the verge of becoming an erection. This is the physical part that leads to my feeling of well being.
