Thanks for the response. What you're describing - feeling a bodily urge to masturbate when viewing porn, even if you'd prefer not to - is very common. We're kinda designed so that our bodies respond to sexual stimuli. Many people can relate to that internal tug-of-war between an impulse and a conflicting desire.
From a psychological flexibility perspective, the key is to approach those urges with mindful acceptance rather than struggle against them. Fighting with or trying to suppress an urge often just makes it grow stronger, like a beach ball you keep trying to push underwater - it keeps popping back up with greater force (1). Instead, psychological flexibility invites us to open up and make room for the urge, observing it with curiosity and letting it be fully present in our awareness.
This doesn't mean you have to act on the urge. In fact, by giving it space to exist without resistance, you gain the ability to unhook from it and consciously choose how to respond in line with your values (2). You might say to yourself "I'm having the thought that I need to masturbate right now" and feel the sensations of that urge in your body, while still maintaining the freedom to decide if acting on it is truly what you want.
Imagine for a moment that a dear friend or loved one came to you struggling with this same dilemma. How would you respond to them? Most likely with compassion, understanding, and encouragement to be kind to themselves as they navigate this very human challenge. We could all benefit from extending that same caring response to ourselves.
At the end of the day, you're the expert on your own life and what matters most to you. By practicing acceptance of your inner experiences, unhooking from unhelpful thoughts and urges, and clarifying what you truly value, you can develop psychological flexibility to pursue a rich and meaningful life - whatever that looks like for you. That means that there's no one "right" way to relate to masturbation and porn. The invitation is to approach it mindfully and make choices that align with the kind of person you want to be.
