As a rule, I don't bring it up.
If your partner is happy, the weight will pile on. It's definitely a thing.
If you're the type that has to engage in feederism as some core part of your sexuallity, I recommend you date exclusively people on FF/curvage/fet/etc, who are confirmed to be into what you're after.
At the end of the day, all of / this/ is something I could take or leave. As long as my wife is happy, I'm happy.
Is it a huge(lol) bonus that she has gained around a hundred pounds since we first started dating? Hell yes.
We have been together for over fifteen years, and in all that time, I haven't had "the talk" with her but she has definitely come to her own conclusions and teases me about it.
A few years ago I was working a lot of over time. She called me and asked if I could cut out early that evening. I started to explain, "Well, no, we're right in the middle of something and..." when she cut in to explain that she had been hanging out with her sister and they had split an edible her sister had made earlier that day. She thought it was a lot stronger than they expected and she was freaking out a bit. Oh, and that she and her sister had just ordered four large pizzas but her sister had passed out and they were going to be there in about fifteen minutes...
I took a beat and said, "I'll be there in thirty minutes."
Twenty minutes later, I was at my front door with a pint of mocha ice cream.
