Depends, I usually use cute as a normal word, why sexy I usually use in terms of like shooting games like "oh that was a sexy kill" or "oh that weapon looks sexy", while cute I use like OH THIS CHICK IS KYOOT
Depends on what you mean. What sort of sexy are you talking about? What sort of cute are you talking about? In terms of my personal perception, I'd choose cute, but you can see these qualities however you choose, so the question becomes a little vague.
Honestly, cute is the closest thing to turning me on I'll ever get. Sexy just doesn't do it for me. It's one of the main reasons perverted girls have charm. I'm not a pervy kind of guy, so it's cute. And really it all just boils back down to cute.
Besides, I don't like how sex feels so why would I want to sex things. Who wants to screw when you can massage and cuddle. -w-
I feel like I could take in and be around cute all day everyday. There's not a time where cute isn't prudent in some way. Even while I'm angry, cute can help mitigate that.
Sexy, on the other hand, has times where I don't feel like taking in sexy. I like sexy, as I'm red blooded and historically a creature of impulse. But there are times and places where I just don't want to deal with sexy. Still, when I do I feel more strongly about sexy than I would cute in the situation.
So I guess I go with cute since it's more versatile.
Sexy is okay, but having a cute girl will make guys stay away I'd say. Like, if I had a sexy girlfriend, well, a girlfriend at all, guys would be hitting on her. A cute girl will be more uh, well, less likely to fall for someone else I feel. I don't know why.
