Question
My girlfriend recently went out on a night out on her own something she usually does. When she arrived home she was quite drunk and asked me to come upstairs with her. Normally, it's tight where i could only insert 1 finger. This time her opening was wide open. Open to the point where I could have inserted 2 or 3 fingers. This was not a normal thing for her in the time we've been together. Is it possible that the opening was like that because of penetration of something else? I stated that she was wide after and asked her why she would be like that, she gave a response of i don't know why maybe because i was aroused. But she has never been like that before. Truly i think she had cheated on me that night, and i don't want to stay with someone who cant be faithful to me. should i be concerned?

Answer
I'm no doctor and one of our experts in the womans health area might help give you more insight on how that works for sure.
In the research I've done over the years It's my understanding that the "width" of a womans opening is made to expand and contract. For example, the anus if it is penetrated will stay open a while and then close over a period of an hour or hours. Where as the vagina will do it quite suddenly. The only way for the vagina to stay "loose" is if there is actual tearing and the tissue is damaged such as in child brith.
Now her explination of "I was aroused" is a feasable one. The vagina will "prepare" for penetration when a woman is horny enough and will expand on it's own. This is why virgins or near virgins are so desireable to men, of course the mental aspect but because during a womans first few times the body does not yet know how to expand propertly and does make a tighter feel.
I don't want to get into personal experience on this one! haha but in some cases with men they will have the inxiplicable erection or for some reason be only partially erect when they are clearly aroused. I believe that erratic nature is the same with women. One can be horny and not yet wet, or not at all horny but wet. One may be horny enough to proceded but not to the degree of rediness physically in that she is "open" for you. It is a muscle a woman can control and it's quite common a woman naturally or intentionall "grip" during penetration and perhaps she did not this time.
Above that, unless she left her "friends" place unsatisfied, she should have been tightened back up by the ride home. It might be more likely that she danced with a man at the bar and got increadibly horny maintained horny and came home and took it out on you. Check that with one of the womans health experts - because it may take longer than I think but I estimate a few minutes and it should be back to normal.
Now how long have you two been together?
I want to know if this is truly the only reason you think she is cheating or if this is the closest thing to solid proof you have? Were you cheated on before and are sensative to it? Or do you deep down have a gut feeling that she is? In cases such as that I always reccomend you listen to your gut, not pick little things to start a fight over - because cheaters will always have an excuse. But wait until you've seen enough to know of sure and just get out without word.
