I have never been a fan of this perineal massage business, i'd never heard of it until i bought one of those pregnancy and birth books, it came with pictures and everything, to be honest, i was grossed out like you wouldn't believe it

, also during one of our birthing and parenting classes, we were actually shown one of those inflatable balloon like devices that you put into your vagina and then inflate to help stretch the skin to prevent tearing... the only thing i could think of sitting there in the class was "what the hell..."
I didn't do any of those either and it didn't matter for me, they had to use the suction caps to get my son out quick because he had his umbilical cord wrapped around him so there was no time for my skin to stretch, i was given an episiotomy that led to a second degree tear, i got several stitches but they were all dissolved and gone by the end of the second week.
I think how well you heal from episiotomies depends on what degree of tear you end up with.
