yes, turn up the heat should do the trick.But do not overdose it 'cause it can be just the contrary.How exactly is your relationship?Does she expects u to act differently?She’s bored or what? Any quarrels recently?It’s just an idea, but if she wants u to be more like bad boy tipe as to turn her on you might try using a verry smal amount of Instant Jerk.This would give you the Bad Boy look (and behaviour as it effects u too so do not od it , ok).Or if she finds u too agressive or misbehaving u might use Instant Gentalmen as to smoothen your appearence…
