Some Raven theory then some Raven nsfw weirdo sin. Don't ask, you've been warned.
When Raven's intimate with her s/o she'd want to be blue, her natural self for her s/o to be someone who cares for her and would make her feel truly loved since even Charles mr 'mutant and proud' always told her to look human even at home
(But how could she because there are no visible openings? for her when she's in her mutant form, not even tits.
Raven could easily turn into anyone, any shape any size and gender or whatever for it, but can't she do anything intimate with her s/o while being herself? I'm sure that would be hard on her because she wants her s/o to love her for her.
Maybe if your going down on Raven and start to push in (let's say to finger her) that an opening would kind of appear? like her mutation just automatically covers it but it's there and if you were to tough her there it would open
(and let's going with that last thing for a moment^^)
Your eating Raven out and her hands are twisted in your hair, she's squirming and gasping so much at the feeling your giving her and her scales are out of control and just keep flipping (but staying her natural blue just flipping over and over) and it's kind of tickling her since it isn't stopping and she's already a moaning and panting mess

FanfictionA few X-Men thoughts I came up with, mostly headcanons and a few oneshots from time to time, put a few Avengers headcanons in here too (mainly Peter because I love him) And now, a bit of Hellboy & Co. too, because we're all sluts for superheroes
