Thanks for the responses

I have a couple questions left. As far as lubrication goes for using the flesh tunnel, is it recommended to use lubrication other than what my penis naturally produces? Would something like vasoline be acceptable?

Also, I'll be asking my doctor for some betamethasone to help speed up the stretching. Should I be asking for the cream or the ointment? Is there a concentration I should be asking for? Finally, is one supposed to apply it on the outer part of the foreskin along the tight band, the inner part where the flesh tunnel is expanding the skin or both?
