I want to experience saying "no" to a woman

For sex, I mean. Okay, I actually have. I was in a long-term relationship with a woman and we had just eaten a high-quality meal (which I cooked) and I was super full and not in the mood. I say down on the bed and she lay beside me and started coming onto me. I was like, "Not right now, babe, I'm too full." She went apeshit all offended. I remember her exact words: "What are you some kind of faggot?" That's my one and only experience saying no to a woman for sex. I want to experience saying "no" to someone I've never had sex with. My "no" was actually a "not right now." I want to say, "No, I don't want you ever." It will mean, "No, you have no power over me."

If anyone has had this experience, speak up.
