I haven't mentioned a single thing about the number of sexual partners she's had. She could have said 2 for all I bloody care.
My point was that some people find it embarrassing to have personal things aired, either their own or that of their partner full stop.
So if she was asked 'How many people have you slept with?' and she answered '2', you would still feel the same as her saying '110' would you?
You would consider that inappropriate and that she should have refused to answer? No. The problem that everyone has (if they have a problem) is the large number.
If someone at a reunion said to me, 'oh, you went out with blah blah, what was he like in bed? tell me about his cock...' and I said, oh, he was wild in bed, we used to do it ten times in every position and his cock was enormous.' DH would probably be a tad upset.
Exactly. And she didn't do that. She simply answered the question with a number. Which is her business and her right to do and does not reflect badly on her, or her partner. Unless someone judges her as a 'slapper' or some other insult, for having lots of sexual partners.
That's all it is. Plain and simple. The number is the problem for some people. If her number was 2, there would no issue, even if she told people.
