So I've posted this situation before elsewhere, but didn't get much advice and ppl thought i was fake 💀. but I'm lost right now and have no answers.

Basically my twin brother's ex cheated on him with a guy with a bigger dick.

He confided in me that after this happened, he feels sexually worthless. He's been addicted to cuckold porn. He's insecure in himself and his dick size, depressed, and suicidal.

He's so insecure and has no motivation for anything. His self esteem is so so low.

Hes also into some extreme stuff tbh. Like he told me he was reading porn/erotica on reddit where the wife fucked the husband's bully (the guy who used to beat up the husband in high school, in the porn), and he got off to it harder than ever. And afterwards he felt like killing himself. I feel so terrible for him.

And he's not an unattractive guy either: he's strong, muscular, athletic af and a huge jock (was a former D1 wrestler and teammates with my husband), funny, smart, etc. Even my girlfriends say he's hot, so im not just being biased cuz he's my brother. Oh, and he's a hero too: he saved me from being raped by my uncle when we were both teens.

And yes, he's been going to therapy. It's not working; he's still depressed, suicidal, insecure, etc. I've asked for help from literally everywhere, idk what to do now.

I can't sleep right now. Im so so worried for my brother. I'm worried he might harm himself any moment.

Any advice is much appreciated.

TL;DR: Brother's ex cheated, he's been addicted to cuckold porn, feels suicidal and worthless sexually. He's been going to therapy, but it's not helping.
