"Fathers don't teach their sons how to masturbate!" - Waldon, Two and a Half Men.
And it's a damn shame because it is through masturbation that we learn about our sexual response. And it is in our pubescence and immediate post-pubescence that we need to learn so many things about the whole package. How else will we learn that we have control over our orgasms - that we can delay cumming or we can have rockets of jizz spewing within a few minutes?
Use your time this month to learn all you can about your cock and its responses. Not only will it enhance your masturbation for life, it'll make all sex better!
Besides, learning can be fun and dad should know and have all kinds of things to teach on how to use and enjoy what we've got.
