Women: Personal question?

Hey, girls... Sorry to get a little explicit, but I had a weird thing happen the other day with my husband. He was using his finger on my for maybe a total of 25 minutes. I had either three or four s - I can't remember. He took a minute or so break in between. However, when he took his finger out, it was wrinkly! Like when you take a shower too long and your fingers wrinkle. That had never happened before and I was totally weirded out. We probably both were. This isn't the first time I have had multiple s. He is pretty attentive - we have spent even longer and had more s than this time. So why was this different? I wasn't as wet as I normally am. We didn't need lubrication, though. I wonder if it was actually the Ph in my that caused it. I have been feeling out of sorts down there for a few days - could this be it? Has anyone had this happen? Serious answers only, please.
