I have a Pavlovian response to cumming. I instinctively want to eat it. My ex gf conditioned this in me. I really can't shake it these days. She would not let me cum unless i ate it. With my current gf, after sex, on occasion I have gone to the bathroom, telling her I need to get some water and then removed the condom and eaten the contents.
When my gf cums, again the instinct to look for cum on her body or inside of her to eat is still strong. She thinks it's gay so I don't do it in front of her.
