There are a lot of people still having fears about wearing diapers because of anal stretching and stuff like that, also when you search the internet you can find some nasty shit being said about anal stretching. Of course you have to be careful and take a lot of time, but there is no harm in stretching your hole whatsoever, for the people that had doubts.
Yesterday, after not stretching my hole for over 4 months easily (I sometimes have those periods when I just don't feel like it), I cleaned my hole and watched some porn after and I got so horny that I just wanted to stretch my ass. I picked the biggest dildo from my collection (the Super Lance Dildo, 11cm across), I figured I wouldn't be able to get it in beyond the head but I just wanted something big in my ass so I lowered myself on it. To my happy surprise it took me less then 2 minutes to get beyond the head and I don't think I ever fucked this dildo so hard, I bounced on it getting the dildo in and out completely getting a bit deeper every time. I think I lasted 5 minutes before I came and almost fainted by the sensation. after 30 minutes of relaxing on the bed I headed for the shower to clean and noticed my hole had already closed again being as tight as it was before. I think this is so beautiful, from an 11cm wide hole to barely able to stick a finger inside after just 30 minutes is incredible. Of course my mind now and then wants my hole to be gaping forever, but that's just not how your sphincter is build, it will always close again.
So yeah, long story short. if you still have any scary thoughts about stretching your own hole, just know that when you build it up slow (it took me over ten years to get where I am, so don't rush anything!) you will have the most fantastic orgasms and sensations you won't get from anything else in the world. Your hole is capable of more than you think.
