When I first made my OKC profile I was oblivious to this (I feel like the gif of the rabbit from Arthur being surprised that people lie on the internet) and just put up a couple of selfies, and when I asked a male friend to look at my profile and see why I wasn't getting a lot of responses, he was like "You only have face pics, guys think you're fat." That's also how I found out putting your body type as 'average' means you weigh 250lbs.
