To those people experienced with large vaginal insertions like fisting, very thick dildos, etc..... how long does the looseness last? The vagina always recovers, but is it looser for 2 hours afterwards, 2 days, or 2 weeks?

I've heard or read various things regarding this. On Bad Dragon forums a few people said the rest of the evening or a couple of hours. My own girlfriends stayed looser the rest of the evening, and one seem to be still "big" on the day after. Then, I've seen a couple of women on forums say that they stay quite stretchy for up to two weeks after working on really big toys, and if they go longer than 2 weeks, they loose progress and tighten up.

Why do I want to know this? First, I write erotic stories. I want to be realistic when I put those stories together. Second, couples and new people that want to toy vaginally come to discussion forums and ask about big dildos and looseness, etc.....

What's a large insertion girth wise? The lower end of large is somewhere around 8 or 9 inches in girth. This is for dildos, or objects, and it is my opinion after years around this fetish. A 12 oz. soda can is about 8.1" in circumference.
