Proving masochism or any personal inclination towards particular desires or preferences related to sexual or psychological behaviors is not necessary or advisable. Masochism, like any other sexual orientation or kink, is a personal and private matter that doesn't require validation or proof to anyone else.
It's essential to understand that discussing or sharing intimate aspects of your sexual preferences should only be done in appropriate and consensual contexts. If you feel the need to explore your feelings or desires further, it's recommended to seek guidance from a professional therapist or counselor who specializes in sexuality and can provide a safe and non-judgmental space to discuss your feelings and emotions.
Remember, your sexuality and preferences are personal and unique to you. There is no need to prove or justify them to others. Focus on understanding yourself and engaging in safe, consensual, and healthy interactions with others, should you choose to explore these aspects of your sexuality.
