This is actually an interesting conversation, and the insults and ad hominem attacks really don't reflect well on you. Rather than attack you back, I'll give it one try to have a rational discussion with you. To have a proper discussion, we have to know what the terms of disagreement are even on. Your responses show you have absolutely no idea what I even said, or what my position is. But here I'll try to correct you.

I'm someone who teaches pelvic floor strengthening and has actually studied this topic both during and after university - this dude is clueless. There is no correlation or causation between number of sexual partners and tone of the muscles in the vaginal wall.

First of all let's get this clear. It's not the number of sexual partners that could theoretically cause decreased tone. Instead, it's the product of both the size of the object and the duration of time that the vagina is being stretched. Whether that be one or two childbirths or intercouse with a well endowed person hundreds of times. So on that account, you say there 'is no correlation or causation between number of sexual partenrs and tone of the muscles'. Please back that up with scientific evidence, as to my knowledge there is none. All we have to draw off is our understanding of anatomy and physiology, specifically related to smooth muscle and connective tissue and the effects of distension.

The smooth muscles in your stomach wall stretch after a big meal but unless you have ten massive meals a day the stomach returns to normal size with relative ease. The average penis is not big enough to provide a comparable stretch and the vagina can return to normal size perfectly well for the rare case (ie not you) that does stretch it. It's interesting you say this, because they've studied competitive eaters and their stomachs are chronically enlarged and lead to problems with motility and innervation and decreased muscle tone, called gastroparesis. So again, our understanding of anatomy and physiology demonstrates the effects of stretching a cavity lined with similar elements.

And yes the muscles of the vagina relax during arousal. But your skeletal muscles also relax during sleep. You sleep for a third of your life and you're not a floppy mess. I suspect that women spend considerably less than a third of our lives aroused. Especially with douche canoes like yourself all over the place. I'm really really lost with what you're arguing here. It sounds like you're pretending someone was arguing that muscle relaxation leads to a permanent decrease in tone and increase in cavity size. That clearly was never said, anywhere. Again if you want to have a discussion, let's talk about the same thing and not make up strawman arguments.
