As Woody Allen famously said in Annie Hall, masturbation is sex with someone you love. It's for that very reason that this sacred relationship should be preserved. Still, people manage to sully the hallowed act. Is there a wrong way to masturbate, per se? Absolutely. There are several, in fact, and people fall victim to them, despite appalling consequences. Sometimes it ends in injury, other times it ends in arrest, but it's dreadful either way. National Masturbation Month may have just ended, but celebrating proper techniques and best practices are evergreen. For all of the fap lords out there, this is common knowledge. For all of the novices, consider it sage advice.
In Public
There are some things you just don't do, and public masturbation falls under that category.
For example, take the dude who was filmed openly jerking off on a bus in Philadelphia recently. Not only did he continue when the woman seated next to him told him to stop, he did it in the presence of a child. Do you really want to risk ending up a sex offender because you couldn't wait to get home? Not worth it, bro.
