Gay, straight, in love with certain sorts of animals… I couldn’t care less.
I grew up poor. I am hoping to alleviate that problem as I get older.
this would do it.
No questions asked, no doubt about it.
Then again, there isn’t a lot I woldn’t do for money.
No way, Jose.
You get $100m
You spend $20,000 on therapy
$5,000 on mouthwash.
$100 on a deed poll to change your name
$1,000 on an aeroplane ticket to somewhere they’ve nevr heard of you.
You’re still well ahead of the game.
Is there a form I need to fill in?
I guess it would depend on what your objection to prostitution is. Personally, I don’t think prostitution is any worse than free promiscous sex - the fact that you are charging money does not make a difference, IMHO. So I would look at the underlying action, not the financial renumeration angle. In this case the underlying action is marriage - a worthy institution.

[ponders slightly different question] Would I marry Anna Nicole Smith and make hot monkey love to her for a hundred million samoleans? Hmm. I actually prefer her current chunkified body to her slimmer look but is that enough? Her face wouldn’t exactly stop a clock but the clown makeup would give me nightmares for years. I break out in a cold sweat just viosualizing the shroud of turnin thing on the pillowcases. The little girl bimbo voice and inane banter would kill it for me I think. I’ve learned I vastly prefer smart, educated, voluptuous blondes to dingbats. Does she talk like she does on the E! show in her personal life. A big risk. Maybe she’s witty and intelligent in private but if I’m wrong I’d be f***ed like Burgess Meredeth with his broken glasses in some alternate universe made for cable Twilight Zone episode. <shudder> I’d have enough money for therapy, moving where no one knows me and a crate of brillow pads to rub myself raw but could I go through with it? Gotta be a solution. Could be something as simple as a big red rubber ball gag. ! That works on so many levels.

I’ll do it
In answer to the “How is this different from prostitution” question.
This whole “marrying for money is bad” is a uniquely modern Western civilization thing. Even in Jane Austen’s time, a major consideration was the guy’s income (although by that time they had moved to the notion that there should be some sort of Luv involved). Marriages were often arranged in terms of the financial benefits they would bring (dowries or land).
There was no thought that this was prostitution (although there were plenty of instances where one or the other party wasn’t too happy with the deal). It was also common for marriages to occur with age differences that would be considered scandalous nowadays – men in their 40’s and 50’s marrying much younger women. Women died in child birth and men needed someone to run the household and raise the kids.
What you are proposing here is just the far end of the slippery slope – great wealth, pure mercenary motive, short duration, and no intent of raising a family or producing an heir. Certainly any pre-existing heirs would object, but provided you can make a case for no dementia or undue influence on the part of the new husband/wife, there should be no legal or moral objection. The real problem, of course, is the “undue influence/dementia” clause. By the time someone hits their 90’s, it’s an easy case to make that they are not necessarily as rational as they once were.
