Only fans

Serious question here because I’m curious!

For those who have a only fans what kind of content do you post? I need extra income but I’m so against OF because I do not think selling pics or videos of yourself is a way to make money.. also because i am very shy and hate my body I am not all skinny and fit anymore after having a baby I weigh 130 and have a flabby belly and small boobs. It’s very discouraging. If I did have a OF is honestly just want to post ass pics because I like that about myself. Also I don’t think it’s right that I share pics of my body to other people because I would not want my spouse doing it. And how do you promote it if you don’t post it on your other social medias? please give me some insight on this topic!
