My wife and I have been together for 2+ years. We have had a lot of sex and her vagina always feels pretty much the same in terms of size. Lately we have been kind of distant and have not had much sex at all. I have been suspicious of her cheating recently. We have spent a couple of days apart. She came over last night and we had sex for the first time in a while. Her vagina felt different. It seemed bigger and wider. I was able to actually fit most of my left hand inside. Usually I can only fit about three fingers in there at the most. I think that this is jacked up! Is she cheating with someone that has a huge penis or what? She denies it and denies it but to be able to put that much of my hand inside without any problem and I could never have done that before... whats the deal... am I stupid for believing her when she says she is not cheating?
