Yeah this is extremely sad. I am only speaking for myself here but I have impulse control issues that were way worse when I was younger. For various reasons one of the issues I had was promiscuity. I would often really regret sexual encounters later because I felt like I had not been myself and was not acting on urges I truly had internally if that makes sense. But, at least it was "gone" as in the sex was between me and one person and I didn't suffer continuous consequences except feeling shitty about myself. It would be such a nightmarish feeling to regret sexual online content and not knowing who had seen it or where it went or how it would affect your life going forward.
