whether or not it is wrong depends upon your view of romance.
Like it or not love is an ECONOMY, just like everything else.
You list on your ad your SHOPPING LIST of traits you are looking for.
You list your OWN goods that you are willing to trade.
And this guy comes along and tries to Barter with you.
'Like a LOT of men, both gay and straight, he realizes he does not have MANY of the items others are shopping for...
So his best bet is to offer you what he CAN, that might be appealing, since he, himself, is not.
The whole concept of "trophy wives" or Trophy boyfriends is that WEALTH is WORTH something.
The only question is, what is it worth to you?
He is betting that you will go on the cruise for the experience...and maybe come to like him for his generosity...and crave the lifestyle that he can afford to offer more than a hot bod.
But, by and large, picking or discarding a potential mate for their looks is PRECISELY as shallow a self interest as picking or discarding a mate for their money.
Either way, you are using them for something YOU want.
The only real question is this... understanding the expectations of the "deal"... does the deal seem fair to you?
Would you fuck a fat smelly guy for a luxurious cruise?
How is that any different from fucking a poor, unemployed loser just because he is hot looking?
As in all relationships, what you are willing to overlook in exchange for something you want depends entirely on how badly you want that thing.
