Funny, I never had a dilation scheme.
I had my srs 27 years ago.
At that time, I had a sort of glass dilator leaved behind into the vagina.
In that round solid glass was a slot for fluid disposal.
I had to include it for one year, two times a day I could take it out, just to clean and in again.
After one year I could let it out for 2 hours , one month later three hours, etc.
I thought it was a good method, the dilator was behind the muscle ring in the vagina, so you could just work after the recovery period.
After a certain time, skin becomes mucous, so not too much problems with lubricating.
Even after all these years I have lost no depth.
it was a bit uncomfortable sitting in the beginning but, hey...everything has a price.
