Do guys have Periods?

When I say "do guys have periods" I don't mean that they are exactly the same. I know they don't have a cycle like we do and bleed and everything, but do they still have one. Because once a month my boyfriend is very moody and sensitive, he doesn't like to he touched, and it all kind of happens around the 12th of every month. Then the next week he is fine and back to normal. I'm just curious about why he acts like this.
