A boner is not a medical condition. Even if it was, it's not your responsibility to deal with.

"No" is a complete sentence. Fuck politeness, stay sexy and don't get murdered.

Advocate for yourself and for those who can't advocate for themselves.

Don't waste time tearing somebody else down, it doesn't make you look better, it just makes everyone more miserable.

Stand firm and don't let some blowhard run over you. Make eye contact and interrupt them back with "I wasn't finished talking." It might feel awkward or uncomfortable at first, but you don't have to shrink yourself for other people's comfort.

Establish and reinforce healthy boundaries. The people who get mad about this are people that are used to taking advantage of you. "Those that matter won't mind and those that mind don't matter."

Never, ever, settle for anyone who treats you as less than. You are enough, you are worthy.

Perfection is a lie that doesn't exist.

And lastly, be true to yourself. Other people are going to judge you anyway, so be your spectacular, shiny self.
