My advice would be to just be yourself and work with people you can trust. It certainly helps when they have experience in the field.
With OnlyFans, you are in complete control of your content so don't let anyone pressure you to do anything you don't want to.
Be comfortable and proud of what you do and what goes up. The large proportion of your fans are people you know that now have the opportunity to see you naked.
If you decide to do it, own it, and be proud.
I look at my content sometimes and think "Wow, is that really me!?"
