What Aunty wants to know is: How could it be possibly any business of yours what the woman you love got up to six months before she ever met you? Your only legitimate concern is with what she has been up to since you met. You've known her for six years now; during that time have you both been completely faithful to each other?

Then, what else really matters?

I think the blood on the bed confirms that your wife did not lie to you about being a virgin. If you try to investigate her previous romantic life in more detail, or to confirm how she was almost not a virgin, then Aunty guarantees that you will learn things that you don't need to know, don't want to know, and cannot benefit from knowing.

The lie detector is a lie. Use of the lie detector cannot expose when someone is lying. Faith in the lie detector is a destructive addiction that allows a person to avoid and shirk the most important duty a human can face: to decide whether to trust another person.

Now, Aunty wants you to go get your wife and sit her down across from you, and then both of you recite the following vows:

We are a marriage. We trust each other. We will not allow that trust to be damaged by uncomfortable thoughts about what our life was like before we met.

We are a marriage. We trust each other. We will not, now nor ever, delegate that trust to an unproven pseudo-science or a soulless machine.

We are a marriage. We trust each other. We will not look beyond each other for confirmation or validation of that trust. Our happiness is not for others to decide.

Aunty also gives you permission to tell that cousin to go piss up a rope.
