I am a 51 year old never married virgin. I am trying to facilitate (along with prayer) finding a husband. I would think a born again man would appreciate a virgin for a wife-everything in life has to be learned-driving, riding a bike, etc. I would think they would appreciate someone with high enough moral standards to have "saved themselves for marriage". What is everyone's opinion on this?
I think that's awesome. If I were unmarried and looking for a wife, I'd be looking for a virgin or else a widow who'd been a virgin before marriage, faithful after, and celibate after widowhood. They may be rare, but there are men who want to only marry a virgin. And there are men who appreciate it.
If a Christian man doesn't appreciate a woman waiting for marriage, IMO, there is something wrong with his morality. I'm thinking of men who think lowly of women for being virgins. He doesn't value something the Bible presents as valuable. That's my personal opinion.
As far as marriage goes, if you want to pursue that, that is well within your Christian liberty to do so, unless there is some reason not to (e.g. specific direction from the Lord.) But I'm thinking of I Corinthians 7. If you are content at this point to remain celibate, why not just stay that way and dedicate the time to the Lord?
At 51, the dating pool is smaller. And the pool is full of divorced men, men who divorced for who-knows-what reason. There are some men around your age that haven't married. I know a second generation Japanese man probably a couple of years older than you who never married and always wanted to. I think he's a virgin, too. But he's very self-conscious and may not be married because of being shy about women, and he'd prefer a Japanese woman. His church has a church-plant in Japan. I've told him he ought to go to Japan where Christian women greatly outnumber Christian men and ask a pastor to set him up. From what I hear, he'd be a rock star.

Anyway, you may find someone who has never married who is similar to yourself in that way.
There are also widowers, too. A widower who had been faithful to his wife who didn't have an ex in his life, that could be a good alternative, too.
