I am a virgin male and I'd like my wife to be virgin too. Is it normal?
Convince him for what? And what is the need to convince him? He is not categorising non-virgins as sluts, he is not judging non-virgins. Then what is the need to convince him and about what?
It's his life, his marriage. He has a right to certain preferences in his life. We all do, we all have. In a marriage some people go for looks, some go for professional stability, some for money, some for this, some for that. We don't convince them, then what's the need here especially when he is not judging anyone.
