Hi @sexifooks 
Welcome to the forum!
I was just going to link to @Blonde_Bunny 's topic on selling underwear but @Wood_Wow got there first 
.
@Mint-Monster 's topic Onlyfans/Fansly Journey has lots of useful info on getting started online.
Can’t offer any first hand experience myself but lots of knowledgeable people on the forum who can hopefully help you.
