I feel that a lot of men have the idea that a woman calling them "adorable" or "cute" is a bad thing and means that woman isn't sexually attracted to them, but it's usually the opposite of that.
I'm way more attracted to cute men than masculine types. I feel kinda bad when I call them adorable to their faces though.
The reaction is usually insulted.
Listen, you can be adorable and sexy at the same time. I call my boyfriend adorable a lot and it's definitely a good thing.
It has a lot to do with gender roles society levies on men. In our world men are not supposed to have emotions and they definitely aren't "supposed" to be cute or adorable. A man giggle?
