Bingo's Maidenless Curse

You worm your way into others' minds to sew seeds of doubt. Choose one creature who can hear you within 30 feet. The creature must make a Charisma saving throw against your spell save DC or have disadvantage on all Charisma checks against any member of the target creature's romantic/sexual preference. Each time it fails a Charisma check in this way, it takes (2d6) Psychic damage. After every Charisma check made in this way, whether succeded or failed, the creature may make the save again, ending the effect on a success. Aromantic and/or asexual creatures are immune to this effect.

At higher levels.

For every level spell cast above 2nd, the target takes 1d6 more Psychic damage per failed check.
