I can see Namor being affectionate. Not>uwu cuddles snuggles
but he'd bring her close, brush upon her head, stuff like that. The one person I cannot imagine coming anywhere close to that is Doom. He'd be disgusted the moment he got his post nut clarity and realised he was touching another body. He'd start noticing the odd wrinkle, the odd way feet are shaped, the peach fuzz, anything and everything would be heightened. I genuinely cannot imagine Doom having "sex" or "making love". He abstains and then reaches a maximum overdrive where he cannot keep it down anymore, he fucks violently and that's it. I think it's why he gets along with Le Fay. Ultimately, he's not made for normal, human things. It's not even about his face. He just cannot bear it. I'd say he's more comfortable killing and waging war, than having sex. Can you really imagine him laying his head on his pregnant wife's belly or something? He'd probably even be disgusted at the word "belly". The man wears an armour 24/7.
Anyway, I got sidetracked there, but Doom and Namor are VillainBros, so he popped right into my head. Anyway, like I said, I can see Namor being "affectionate". He courts too much to not be so. He's a genuinely good lover. But he's just not Parker or whatever else who'd cuddle after sex and such, or would laugh at pussy queefs.
