4. People Don't Tend To Remember The Last Time They Masturbated
Unless it was last night or two minutes ago, can you really remember the last time that you had a party for one? However, this is more common with men as it is with women because every time a man ejaculates, they lose vital neurochemicals involved with concentration and memory. Having said that, the other reason that people don't tend to remember the last time that they jerked off can potentially be attributed to the thought process that masturbation is still seen as taboo and inappropriate. They might not even own up to it. But still, it's not like everyone marks the calendar after they've gotten a little bit frisky with themselves.
