Hey everyone i recently started dating a big girl but it doesn't seem to me that she's into federism any tip on how to know if she's into it or if i can convince her to imbrace it?
I mean, you are welcome to ask, but there's no promise she will want to get bigger.
If she does not want to gain, don't push it. It's her body. If you two break up and she only gains for your pleasure, she is going to hate herself later.
