For me it works well, I'm an expert in Nunchaku which mostly involves kicking and handling the weapon itself. The advantage of Nunchaku is that it looks very cool and flashy to an innocent observer. Once you learn it just pick a set of stainless steel ones or aluminum to make sure she can't learn it without dying first lol and then watching you do it will be a good sight inviting for sex.
My girlfriend often came suck my dick after watching me train, I told her why do you humble yourself sucking my dick like that? She said that watching me do nunchaku moves was a turn-on lol. If she's a control freak with an induced sense of female superiority she will hate it but what man would domesticate such an annoying life partner other then a sissy jerk-off?
