We have kids, all vaginal births, so I know that is not the issue. I do feel that fingers probably provide a little different type of friction than full PIV intercourse so I don't know that comparing the effect of the girth of fingers and a penis is quite the same thing. From our experience I don't think it is a tightness issue, more just an effect of friction resulting from PIV causing regular mild soreness. Sort of like trying to MB without lube. Too much rubbing with not enough lubrication can cause soreness/tenderness without resulting in any permanent or severe damage.Link+Zelda wrote: ↑Thu Feb 17, 2022 9:43 am I am circumcised and fall in the "average" range. Except for the first few times we had sex (didn't use lube...), she hasn't experienced regular soreness.
Early in the relationship, we did some internal fingering, and going beyond 3 fingers (or even just at 3 fingers) could cause residual soreness. Now, after years of activity and birthing kids, plus with the addition of the vibrator to really get her going, there's no soreness with four fingers or even four+the thumb at certain times of her cycle. I'm pretty sure she could take close to twice my girth without being sore if she was properly aroused and lubricated. Given that, I do think that length of sexual activity plus whether a child has been birthed vaginally factor into this question.
As I stated prior, I am well above average in both length and girth, but aside from things being a little tight when we were first married, it has never caused any other problems, especially after vaginal births. In addition, my wife has responsive desire and often has trouble becoming fully aroused prior to PIV, even with extensive foreplay, yet will often get highly aroused very quickly after we begin PIV. It may be an issue with her internal lubrication, though lube or CO we use liberally have never seemed to make much of a difference.
While the poll I posted is only a tiny sample size, it is interesting to note that so far, almost 20% of respondents indicate a similar experience with soreness in their marriage. How many wives in that 20% also have responsive desire? I guess that would require another poll to find out.
