Anon in the comments remarks:
I thought your narrator was dating a divorcee.
In which case her being a virgin would surely set off far more alarm bells than it would silence.
Which reminds me of a joke.
A man and woman meet, fall in love, and get married. On the wedding night the man places his new bride on the bed whereupon she says, “Please be gentle with me, for I am still a virgin.”
The man looks at her in surprise and says, “But how? You’ve been married three times before.”
The woman wipes away a small tear and says, “Ah, but it’s a sad story. You see, my first husband was a psychologist; all he wanted to do was talk about it. My second husband was a gynecologist; all he wanted to do was look at it. My third husband was a stamp-collector … oh, how I miss him!”
