My very first girlfriend who I’ve dated for now 6 months is plus sized, she loves food, and loves it when I bake for her, we both believe in waiting for marriage; but I never told her that I am really into Feedism, how should I tell her?

Ask if she wants to talk about the things you each find attractive or the fantasies you each have. I'd normally say that after sex is a good time to do it, as part of aftercare, but any time while cuddling is a good time. Show openness and curiosity about her tastes, and be up front about being hesitant or worried about her response if that's how you feel. Tell her that this is a part of you you think you're ready to share with her because of your trust in her, and that while you don't expect her to indulge your fantasies in any way, be honest and say that it's something important to you.
