It’s basically an open wound/artificially created fistula. The body’s natural response to such a thing is to try and close it - the constant and regular dilation is to try and stop that.
They smell for a variety of reasons. Sometimes they use bowel tissue to create it, dead skin cells accumulate and break down as part of the bodies constant attempt to heal the ‘wound’ and there is no natural lubrication or self cleaning like there is with a real vagina.
Also, in the case of ‘neo vaginas’ that have been created from penile inversion hair can grow inside them. I feel a bit sick even typing that.
