Hmmmm, I must be in the minority. I'm like a cross breed of you fellow posters, lol.
You see, I LOVE the thought of anal, it turns me on so much! Just reading this thread makes me hungry for it, haha! But, like many others on this thread, I find it very uncomfortable, sometimes painful and, yes, I agree, like I need to poo! Lol.
It frustrates me so much that I cannot do it.
I have a douche, a multitude of anal lube, a million anal toys, I have tried everything! I have tried roughly 20 to 30 times, and only 2 to 3 times were really enjoyable, I fully got off on it and the feeling of needing to poo and the discomfort subsided. All I know was that I was very drunk and my labido was sky high, that was how I was able to work towards it.
For those who just have the problem of feeling like they need a poo. I found that once you've gently worked him in, your relaxed, slowly pick up the speed, picking up the speed (but at your own instructions and pace) helps eleviate that feeling, and it then becomes enjoyable. This is just in my opinion though that worked for me, we are all different, so please don't take this as a definite answer to the poo problem, lol xox
