Okay, yall gonna hate me, but I finally decided on my answer.
Fuck - Law. He's clean and weird and I'd probably have good sex with him. He's also a bottom works out better for me who was an in denial service top for a very long time lol.

Marry - Kid. He's blunt. He has problems but for the most part he has his shit together and goes hard for the ones he loves so I might be good there.

Kill - Luffy. The man would come back anyway, everyone's failed "killing" him, and I just can't sleep with a guy who I know doesn't wash under his foreskin or between his asscheeks. 😔
