This is actually a serious question, it seems your can tell when she is or not, but what actually qualifies it

Three. You have to allow for some wiggle room (pardon the pun) when it comes to finger size and a person's body structure (Some are just built a little loose, for real).

on a womans point of you  there is no way you would know for sure if were having an orgasm, it's not about screaming or anything like that, you'll never know....unless she's 100% honest with you if thats the case i would question if she's truly a woman see the original birth certificate if you know what i mean

It depends upon the person.If he/she is a straight cut and true person then ask him?her directly.I am sure you you will get the truth.But never expect any thing from the hippocrates  who will always give you the incorrect information.So its important to differentiate between them.

She might be being nonchalant?

Just because that's on there doesn't mean it's the truth. I have seen people put lots of thing that they aren't.  Talk to her and get to know her.  That's the only way you will know for sure.

MAY BE PASSING TIME WITH YOU.  YOU MAY BE MISTAKEN TO UNDERSTAND HER.

first do you really have any true evidence that she is... if not she will not appreciate an accusation... maybe she is going through something else?? maybe you should try just approaching her in a very caring manner and ask her if something is bothering her and being there for her.... sounds like something is up but you don't know what and don't create scenarios in your mind..... because you don't know

How do you know what she said if she never told you, and even so, how do you know if what she allegedly said is the truth if its based on heresay?

you'll just know. simple as that. but check with your friends; they'll judge her from 3rd point of view. (sometimes it'll backfire)

No idon't think so she is just trying to honest

Look at his or her eyes deeply. You'll get the answer.

Because she can. That is why your question is about using a good duy.

The mere fact that you are wondering shows that you love her and deep down you know it

You need to ask her about this.  Gently, not accusingly.  <---VERY important. No one here can tell you because no one knows what's going through her head right now.  Everyone's different.

It sure sounds like it.  Maybe she is actually a he.
