I've never met a guy who couldn't make up his mind.
Either he wants to sleep with the chick, or he doesn't. Either he wants the truck, or he doesn't.
I hate to say it but men are fairly simple to figure out, we have our hobbies, our likes, our dislikes, and we simply make up our mind and that's it. We might change it years later (Like someone who was against gay marriage, being for it now) but its not something we will flip flop on every week.
