There's a great story in the book Bossypants by Tina Fey. It goes as follows.
“Amy Poehler was new to SNL and we were all crowded into the seventeenth-floor writers' room, waiting for the Wednesday night read-through to start. [...] Amy was in the middle of some such nonsense with Seth Meyers across the table, and she did something vulgar as a joke. I can't remember what it was exactly, except it was dirty and loud and "unladylike". Jimmy Fallon [...] turned to her and in a faux-squeamish voice said, "Stop that! It's not cute! I don't like it."
Amy dropped what she was doing, went black in the eyes for a second, and wheeled around on him. "I don't fucking care if you like it." Jimmy was visibly startled. Amy went right back to enjoying her ridiculous bit.
With that exchange, a cosmic shift took place. Amy made it clear that she wasn't there to be cute. She wasn't there to play wives and girlfriends in the boys' scenes. She was there to do what she wanted to do and she did not fucking care if you like it.”
I think about that story quite a bit. As women, we tend to exist in a state of seeking approval, of waiting to be validated. I love that expression, the self-validation. "I don't fucking care if you like it."
Follow the rules you have to in life, but don't forget to also do what you want when you can. If it turns you on and it's not hurting anybody else, do it.
