Is it normal to like 2 very different guys?

So basically I like these two different guys but they are very different from each other. I'm very picky so it's unusual for me to find a guy that fits my criteria, let alone two at the same time. They're both sweet and great but one's an outgoing and "guys guy" but with a soft heart while the other is more reserved but intellectual and sweet. Some days I'll find myself thinking about one more than another but it always switches back and forth. I've never liked two guys at once. I think they both potentially like me back. Also, to the guys of IIN, how do you tell if a guy likes you depending on their personality type? The more outgoing guy seems different around me than with other people ( like he seems a bit restrained and almost nervous when talking) - is that a sign? When he had a gf(now his ex), he talked to me once about how they'd have to keep up a long distance relationship as she was moving. Did he do this to stir up my feelings for him? I didn't think guys talked to female friends about gf stuff. Also, I'm pretty sure that the reserved guy's mom tells him I'm a catch because she always tells my mom how great and gorgeous I am after complaining about his ex gf haha. It's hard to tell if he likes me though because he's always calm, cool and collected. I'm just confused with why I'm finding myself liking two very different guys. I'd love some insight! Thanks (:
