If the belt is well made,it should not prevent you too much movements,but still restrict a bit.Like @Ines said,you could do it,but not at competitive level.But my main concern about it is I think it can he harder to conceal it during sports or dancing.
I wear a similar one,except it is a My-Steel one.I tend to think the cable one(like this one)is the best rear.It is possible to move it a bit when needed for toilet,and use wet wipes to swipe.
James Also, most girls choose to wear it.
Not several of us here...
Katie mom want anal sex to be impossible but me to be able to poo. Is that possible to have both?
Yes,the cable can only be moved a bit.If a man want some anal,there is a risk he get mainly pain,and maybe injuries,for trying it.
