I don’t know whether or not Yash still encounters the same challenges, but I think the following sermon (by Amadassana Thero) would be helpful for anyone who experiences these issues.
He provides some mundane tips for when lustful and angry thoughts arise and one has problems reflecting on their anicca, dukkha, anatta (and asubha) nature due to their intensity.
Regarding porn, he also mentions to think about/look into the lives that the actors actually go through. I remember some years ago I had managed to stay away from porn for quite a few years, thinking I had decreased my lust to a significant extent. I simply managed to suppress it long enough (with Goenka’s method) but it came back to the surface at some point. Then, one day I came across an interview with Joshua Broome, a former porn actor turned pastor. Check one of the longer interviews on YouTube if you’re interested.
Although I hadn’t come across pure Dhamma yet that time, it really helped to see things in perspective. I actually looked up a few flicks he starred in and I felt quite sad and disgusted, in a way, due to what he shared.
