A male verison of a menstrual cycle or a meriod (which females wish existed )As in, their sperm gets expired evey 20-40 days (depending on their cycle). The sperm comes out of their penishole with blood mixed in. They can wear pads and TT (tiny tampons). Their penis hole expands to let out all the sperm, and as this happens they have major testical cramps. Some of these are worse than female menstrual cycle cramps. Males can tell as to when they are about to have their meriod, their testicals grow large and tender. Their mood becomes very grumpy, and rude. So I would advise you to stay away from males when they're on their meriod, keep in mind females that they have it worse than you! When they're on their meriod,their testicals get smaller from all of the sperm lost and they do not experience erections at this time period. After their menstrual cycle (which can last 7-10 days on average) their testicals rapidly reproduce sperm. At this point they feel very sexually aroused and "turned on" by almost anything. Yes that does mean Amanda Bynes gets a boner.
Guy- "Uh, I'm on my meriod Jenny!"
Jenny- "Okay then......"
