Help me name my characters! (Boyfriend edition) (Patreon)

Hey guys, I'm having a little trouble deciding what to name the characters in the story I'm working on. 

For the boyfriend in my story (the one that's going to be getting all the sex), I've got a couple of options I'm trying to decide between. Since this is intended to be part one of a series, I want to get it right - I'm going to be stuck with the name for a while!

A little back-story to help: the character is of latinx descent - born in Chile / Brazil / Venezuela (haven't quite decided) and who migrated at some point to New Zealand, where my story is set. His ethnicity probably won't really come up in the story at all other than informing my mental image of him, which in turn will inform any physical descriptions I include (which I tend to keep pretty minimal so the reader can use their own imagination). So a name that's Spanish/Portugese in origin, or is normally found in South America, would be good - but in a way that's not stereotypical.

I guess I also want a name that's not super formal, nerdy, or pompous. I guess I want something kinda youthful and informal, and I want his name to sound hot, of course. For some reason I tend to gravitate towards four-letter or four-syllable names, or names that can be shortened.

So far I've used Luca in my draft, but I'm open to changing it. So let me know what you think! Pick from one of my suggestions, or suggest your own. 

Disclaimer: I still reserve the right to make the final decision myself, no matter what you vote for! But I definitely appreciate your thoughts and will give them a lot of weight!
