When I am horny, thinking about eating my own cum turns me on, but when I cum I lose the nerve. Why is that?

What you’re experiencing is actually pretty common and can be explained by something known as the “post-orgasmic shift” or “post-nut clarity.” When you’re aroused, your brain is flooded with dopamine and other pleasure-inducing chemicals, which can lead to heightened desires and fantasies, such as the idea of eating your own semen. This state of arousal can make almost any sexual thought seem incredibly appealing, even if it’s something you might not consider outside of that moment. Once you orgasm, however, your brain chemistry changes dramatically. Dopamine levels drop, and your body releases prolactin, a hormone that promotes relaxation and reduces sexual desire. This often results in a sudden shift in your mindset, leading to what you described as “losing the nerve.” It’s like flipping a switch from being totally into an idea to feeling uninterested or even repulsed by it after the fact. Many men experience this same Post-Nut Clarity in their feelings, whether it’s about eating semen or other fantasies that feel less appealing after ejaculation occurs.
