I'm wondering whether it would be proactive to regularly dilate this opening (even with warm oily fingers). I've been abstaining from sex for a year – too painful. Silly me, I've been using a magnifying shaving mirror to inspect my undercarriage nightly and last night it occurred to me to look with a regular mirror. Whoa! I'm a lot narrower than I thought! About two fingers. What I've been noticing in my inspections has been the narrowing and elongation of my perineum. I took that to be a tightening of the flesh from repeated tearing. But now I see it's that the 'shore' of the perineum is sneaking up on the vagina. Like a beach getting wider as the lake's water level drops.
My goal (a modest one) is to always be able to pee. So I think I might make a practice of massaging – slightly stretching that circle every night when applying my oily stuff. Not at the same time as applying Dermovate/clobetasol.
