Well I haven't heard of folks doing this, fully well with the man they are with knowing they aren't just for the sake of it... most of what I have read or seen on this is gals who for whatever reason aren't (not divorced with kids) but wind up with a guy who wants them to be one, or get involved with a ethnic group man that highly expects it them to be.
I know if I was obsessed with taking someones virginity, I'd be out finding a virgin, not asking gals I know aren't to sew it back up so I could pretend.
That was the example in the article, but I expect it's not the usual situation. As everyone's been saying, unless a man's really weird, he'd rather have a cruise or a plasma-TV than fake being with a virgin for the same cost.
