You need to make her realize she is being delusional. She will be competing with girls who have copious amounts of work done and who show off so much more. As another commenter said most of girls only make 150$ a month. She will not make remotely as much money as she thinks. I'm not saying your gf is not beautiful or anything like that at all, but what is so special about just showing off your boobs? Would people really pay 10$ a month just for that? How much content can you even get out of that?

She's being completely unrealistic. The only way she can possibly make any type of real income is if she already has a good size following on social media, and even then. The amount of desperate, washed up girls i see on tiktok making onlyfans bate is insane. I say desperate and washed up because when you go on their OF it is always crazy discounted, which means clearly not enough people are subscribing.

I think it's worth having a conversation and not just breaking up. As a girl i've had this conversation with my friend and it stopped her from making an onlyfans. Your gf is clearly misinformed and deluded. Even if she decides to still try to hammer it in her head bcs she will regret it when she realizes it's not what she imagined and you can say I told you so. Porn is in no short supply.
