I had a flatmatewho was straight and had a really bad breakup at a really rough point in his life. Dude was put on a 72hr psych hold after a meltdown at work.
Then he started disappearing for several hours a night and nobody knew where too, always came back smelling like he had had a shower and had slightly wet hair. When we asked him he said he was going to the gym. It took us a few weeks to realise that something didnt add up, he didnt own workout gear, he didnt have a gym bag, and unless he was pumping iron in jeans and a hoodie and his Timberlands that he wore everywhere he was full of shit.
So I sat him down and laid it out, just said "Bro heres why we dont believe you. Now you're clearly doing way better and its your business but after the psych hold we're just looking out for you, whats up?" he heard about a gay bathhouse in our city and was going and just fucking and being fucked for about 2 hours a night. As you can imagine the 22yo handsome guy was quite popular and when guys are arguing over who gets to blow you next is a pretty good confidence boost to a guy who was a borderline suicide risk a month ago.
