On the female side, isn’t it canonically someone? Like the Celestial Madonna? (Huh, if it’s her, that’s an Englehart character, natch.) Or am I imagining that?
Vampirella
I got you covered, buddy.
On the plus side, they can also be used for women screwing Superman because it would prevent his super-sperm from burrowing through your body and digging into your brain.
Played by Annette O’Toole? I’m totally there!
Who the hell invited you to my sexual fantasy? G E T O U T!
Yes, well, you’re still not invited.
Are you kidding?!? She’s a vampire!
She’d suck you dry!
…wait…oh, yeah.
Spider-Man, if you like to swing.
Catwoman probably wins on the sexy front, but I do believe Emma Frost would be pretty kinky - great outfits.
Gotta love Power Girl though, just for that opening on her uniform. Genius.
It always used to be Batman/Micheal Keaton but he’s been gently overtaken by Iron Man/Robert Downey Jr.
But there’s always Nightcrawler, though he’s a bit too vanilla for me, I fear.
Magneto. Hey, he was a superhero once, for awhile. The comics version, circa around the mid-80s. Not Ian McKellen (I’m not his type anyway).
Dr. Strange would be cool too. He’d take us to another dimension. 
Mystique, hands-down. She’s not just a shapeshifter, she’s a naughty shapeshifter.

The world will know,she’ll tweet about it.
I am morally certain that Nightcrawler has used his tail in a phallic manner.
He’s never struck me as vanilla, though he’d probably be very chivalrous.
Yes, but she’ll also kill you for any reason that suits her.
If you’re that close to her canary cry, I wouldn’t expect to survive.
So religious, is what I feared - I can’t really see him getting down and dirty.
Mmm. And talking dirty to me in German. Yes, please!
I have to say, if you’re making love to a shapeshifter, you’d better be sure it’s not one with an impish sense of humor. Or an outright sick sense of humor.
Yes, but you’d have to be in the Marvel Universe. The problems with that are infinite as well as obvious.l
No love for Doctor Octopus?
He’s big in Japan.
Why do they call him Mister Fantastic?
Oh.
OH!!
