I did quote the funny werewolves for the topic's title but I don't see anything wrong with using a whip. It's a good weapon, you can cause a lot of damage with that thing. However I like better when the Belmonts use chain whips rather than the normal ones. It looks more cool.
Zorro from the old tv series, for example, used a whip from time to time and he kicked asses with it, I didn't think he looked girly using it.
If you associate whips with dominatrixes then you may think it's girly but whips have always been used as weapons of repression and punishment, at least when I hear the word whip my first thought is something like an evil jailer punishing slaves with his whip to make them work faster, at least the Belmonts use them for justice
