Why do you think it is that anal plugs have bases, or moreover, why they have that big plug and then the space in between the plug and the base that rests where your opening is? Do you think it's so that the opening will stay tight in order to make anal sex more arousing (it feels better when you're tighter (in a way-but not too tight, so it doesn't hurt), doesn't it?), or because you want to keep it tight enough so that hemorrhaging won't occur? Any opinions or comments on the subject? I just got to thinking about it.
