Isn't Mammon assexual?

I know there is a whole spectrum of assexuality, but I was curious and it kind of surprised me that he flirted with Leviathan in that sexual way. Maybe he's more of a "occasional sex-drive" assexual and stuff, as far as we know he's not aromantic so he could have a crush on Leviathan without wanting to have sex with her. Maybe I'm just dirty-minded here and his proposition wasn't sexual at all 🤷🏼‍♀️

What do y'all think?
