So, your concept of vaginas is flawed-
The vagina is a muscle. Muscles improve by working out. That's the reason sluts are so popular, their vaginas don't loosen up, they tighten up; same reason women who have kids are tighter after they've recovered. Unfortunately, some women are born with loose vaginas, and people assume they've had a ton of partners, but they were just born that way. It's all about kegel exercises.
That was my point, if you think having sex increases the vaginal cavity, then normal sex over the years would also do so.
Now, the anus is meant to handle penis-sized shapes, but for extremely short periods of time, hence the anal leakage from anal intercourse. Don't do that on the regular.
There's a lot of falsehoods being thrown about in this chat, we absolutely can digest cooked meat, and required no evolutionary change to do so.
We're meant to be a community, based around one man with multiple wives.
