Sentiment about virgins hypocritical

An old high school classmate told me that his girlfriend won't make love to him, which makes him, at 25, still a virgin. He's upset. Last year, he told me the same thing. Essentially nothing has changed over the past year. The girlfriend told my friend she'd only lose her virginity on her wedding night. He said she's very determined to stay true to her word.

It's relatively common for a woman to be a virgin at 25- I've got several friends who never dated a guy until two years after college. When it comes to a man, 20 is acceptable; at 25, it's just embarrassing.

What makes me admire his girlfriend is that they've been together for almost six years. But the problem is - following the girlfriend's logic - if my friend wants to have a first time, they need to get married.
