I've been trying to find the answer for this, but no success. So, I know there are quite a few slangs for male masturbation, such as wank, jerk off... but isn't there any for female masturbation? I'm not looking for euphemisms here, I'm not keen on them. Now, slangs... can be nice.
In order to avoid the risk to pass over a helpful commenter out of distraction, I'd like to say thank you for all the comments to my query.
You were all very very helpful, ladies, or whatever pronoun you want to be addressed by :)
I'm going to stick to 'wank', since it's too awesome not to use, and a word I've always been comfortable with.
