Moaning?

Earlier today, I saw a post that a girl made, basically saying she doesn't ever moan during sex/masturbating and she was wondering if other girls are just faking it. The post was worded a bit rude, yes. But there were some comments that were like "If you aren't moaning, he isn't doing it right" or "you've never had good sex" and stuff along those lines. This made me kind of feel like shit, because I don't moan. When I'm touching myself, I don't moan at all. Moaning takes physical effort out of me, and it makes it feel less pleasurable because I have to focus on making myself moan. When I'm having sex with my boyfriend, I do moan for him, but it's because he likes it. Like I said, it takes effort out of me to moan. It made me feel bad that someone would say that it's not good sex if you aren't moaning. To me, that's just as rude as someone saying that girls that moan are faking it. My sex is definitely good. Everyone is different, and there are some girls that make noise, and some girls that don't. Why does everyone have to be so judgmental of everyone else's sex life?
