No, none of us here at JackinWorld has any sexuality credentials, but we do have plenty of experience. (There's probably over 25,000 masturbation sessions among all of us.) I personally took a few sexuality and reproduction physiology courses in college, and I know a great deal about human masturbation habits and practices from running this Web site for all this time – but that's about it. So if you choose, you can take everything we say with a grain of salt.
Do you find yourself masturbating more often during some seasons than others? Why?
