I dont know if I would refer about selling your daughter for money, can be refered as perfect. I dont wanna say, that you force something on her, that she might actually feel bad about. The thing is, because of her still being 17, you must take in mind (for her) if she will feel her whole life well about it? Right now she might feel ok about that, "He marrying a sexless guy, that will pay 10.000 bucks for it." Can you be sure, that she will be thinking that way about it as well, when she is 30? When it comes to stuff that you did on your own, while being young, you feel about it as "doing life experiences". But if you try to push her about that, then you will become the adult person, that will have to feel responsible for that, and the possible outcome and consequences of it?
As well, that you say, that she actually is not really interested in man and sex. If she later might meet the guy she wants to marry, then she will need to do an divorce from her former husband. If he then does not aggree, anyway what he might say now, then you might have lots of law-troubles, that will make an divorce expensive.
I really do not feel comfortable about it. I am not religious and as well not really into romance-stuff, but marrying should be something special for you, that you do with someone that feels special for you, after you have done a lots of thoughts about it. I´d be afraid that doing it for "earning 10.000 bucks" might lead to ruining that feelings inside of her toward marriage.
