Perfume/cologne items that boost seduction attacks but lower stealth Especially unstealthy against sniffy enemies, like canem or the like (idek if stealth will be a thing but pretty smells are pretty)
Oh! You know how LT lets you choose the species and genders of the random encounters using a menu? This could be like an in-universe version of that. In that case it probably shouldn't have stealth implications though.
Am horny, early morning, wanted some place to drop an idea so I don't forget: The ability to type in how you tease an enemy to better express your character. The game will ask to type in a description and save it, perhaps you can also "tie" in what body part it draws from, like breasts, which will increase your breast-based tease skill.
