Nosebleed, Variant (3.5e Trait)
From D&D Wiki
 Nosebleed, Variant [General]
Like most animes your character will get a nosebleed when aroused.
Benefit: Bonus feat or +1 Charisma.
Drawback: Once a character has established a nosebleed from their attraction to another character/s a heal DC of 15 must be made to stop the bleeding. The character needs to make a will save DC of 15 (+2 for each other character they are attracted to) or in 1d6 rounds have another nosebleed unless away from the character/s who caused it. If partying with said character/s each week with them the will save will decrease by two.
Normal: Most people don't have nosebleeds while aroused.
Roleplaying Ideas: Your character may get a reputation for being a pervert, or will be embarrassed when near an attractive barmaid.
