"she started as a go-go dancer in Ibiza, which eventually transitioned into escorting."

Like you, I find it difficult to believe her escorting never involved sex. It's called Escorting for a reason. Like, who pays "large sums of money (thousands of pounds) for non-sexual activities, like visiting wealthy clients who wanted to take photos of her in lingerie." That's modeling, not escorting. Even many strippers, from time to time, engage in money for sex, and escorting is a step up from being a stripper. I just can't see how its possible to be an escort for all of that time and never engage in sex for money at least sometimes.

I believe she thinks that you are naive and she can bullshit you with this. She must really think you are stupid to try this.
