As a male my pelvis bones are not so open as female ones .
I have a dildo shaped nozzle , what nicesfeelings when it is filling you up, and the dildo is moving deep inside and then to the limit outside , this slowly done is huge , the volume of the dildo is increasing the pressure in the rectum waouw , so nice .
I like anal feelings so I often play with my ass , when masterbating or love making , using medium or large plug or dildo size ,
what is large for me ? 2.5" medium is 1.75" , I hold it in for a 15 -30 minutes , and don't never have a closing problem with my anus . I try a larger plug 3" who was blocked by my pelvis bones , so my ass muscle is souple enough but my bone not .
Why trying this because I have the hope to be fisted by my wife . Far to me to make a record , she have hands just at our limits , she can't fold her hand more , and my pelvis bone don't change .
No anal problems the muscle is quickly closing after the exercises .
