In the lecture, people were stating what the other names are for masterbuation. It got me thinking the reason why boys have so many names for the activity. I think this is because boys will be more open and honest about masterbuation while the girls are a lot less open about it and wouldn't not share this information. All the stories that I have ever be told about masterbuation has come from boys that I went to school with, which consits of them telling each other when and how many times they have done it on a day to day basis's. Girls are less likely to talk on the subject, however i'm not saying we don't do it but we just don't openly talk about it! A lot of men masterbate names can be very violence names like pull the monkey where as female names are more playful and softer.
Here is a video of a father embrassement to talk to his son about masturbation:
