Little known fact about D&D succubi: since 4e succubi can change sexes freely. Incubi and succubi are just different forms of the same monster.

"Oh, hey friend! I just made garlic bread! It's warm enough that you can see the garlic butter oozing across the golden crust of the bread, and steam comes out when you tear a piece off. If you murder all your friends, I'll let you have some~"

And for the warforged: "sudo murder all your friends"

Aren't incubi and succubi the same creatures that just change their form to seduce the desired target?

They're not actually sexy women with wings and little horns; that's just the form they usually use when someone summons them deliberately because it's the form most summoners want to see. They're malevolent, shape-shifting extra-dimensional entities, they're adept at emotional manipulation, they want to drain away a mortal's soul through physical contact, and they prefer having that contact given willingly. (Maybe the soul is more useful to them like that, or maybe it just tastes better.)

They don't need to seduce you. Maybe being a mercenary has severed your bonds to your family and your community? Maybe you've seen things that you wish you hadn't? Mommy understands. Mommy will make you all better. Give Mommy a hug...

Every character I play is secretly asexual, and I don't think anyone has realized yet.

The closest I came to come out of the closet was when my Undead Warlock married his Unseen Servant. It was his best friend, they looked up to one another, respected each other, and shared an exclusively platonic relationship.

He prepped the entire ceremony in secret as part of multiple sessions:

• He asked his mentor to put a 6th level Major Image inside his spell storing trinket, which he used to create the perfect setting for the altar.
• He took a dragon scale from the corpse of a dragon the party had slain, and spent money to have an engagement ring crafted out of it.
• He had an outfit made out of very expensive material for the Unseen Servant.
• He put the Unseen Servant spell inside a custom wondrous item that gave him infinite casts of a 1st-level spell.
• He asked the party's cleric to cast Ceremony.

He then waited for the final battle, and the night before, he gathered everyone without telling them why, took out the ring, cast Unseen Servant and proposed to it. There were a lot of happy noises that evening, especially from the party's cleric :)

The character I'm playing now is a lawful good city watch who is "married to his job", and the Paladin has joked multiple times about taking him to a brothel. Bruh, take the hint.

DM: succubus charms work on all sexes, even asexual and non-sexed characters.
