looks very normal to me. if he were to marry someone in 40s like some virgin then is more surprising.
Your comparison is unfair. It should just be a 20+ vs 40+, and not 20+ vs a 40+ virgin. The 40+ virgin loses out not because she is a virgin, but because she is 40+. Likewise a 40+ who is not a virgin will still lose out.
If the comparison is between a 40+ virgin vs a 40+ non-virgin, then the 40+ virgin will gain moral points over her counterpart for her superior self discipline. And self discipline is a virtue.
If a girl can remain a virgin until 40 as a matter of choice, you too should applaud her parents for good upbringing. It's always easier to lose your virginity then to preserve it.
