The woman who birthed my child didn't remember anything of the actual process, the pain is so bad the brain just kinda blocks it out after the fact apparently. I've read this is fairly common. One thing I do remember is how bad my hand hurt after all that squeezing, I needed like a whole two ibuprofen to fix it, talk about killer.

I remember seeing this ring built specifically for this purpose. It was an unobtrusive metal band and you could synch it up to its pair and it would squeeze your finger in time with the pair's heartbeat sensor, I'll see if I can find it again
I don't believe this is the one I came across but was all I could find with a quick search. The website seems a li'l sketchy based on grammatical errors so I'd do some double checking into it but it seems like what you're looking for. https://my.thetouchx.com/hbring/howto-use-hbring
.ml is another of the tankie triad instances that are typically blocked for context. On lemme.ee for their loose defederation policies and I'll be moving to .zip for the same, but I still block hexbear at the least because of how horrible those people are, rather bang my head against a wall than entertain that cess pool
Only speaking from personal experience obviously. Ass and vagina - yes, vastly different. Vagina is like a really wet warm tunnel with pretty even pressure throughout. Ass has a really tight opening and then less so further in. As for kegels, oh boy yes can you feel the pressure differences. Like squeezing a fist.
I lucked out into being born 5'10, not tall enough to need special clothes, but short enough so the shallow "6ft or nothing" women self filter themselves and I don't have to deal with them myself. I had a buddy who was 5'4ish who was an absolute disgusting human being but always blamed being alone on his height, also have a buddy who 5'2ish and married to an absolutely wonderful woman
