In his last "meltdown" stream, he said if it were legal and there were brothels. He would go and order a big titty goth girl. So I'm not sure if him turning down prostitutes is because he's aware that it's illegal and doesn't want to get in trouble/entrapment. But I'm not sure if Josh has the forethought or self control for this. But it seems to me, that whenever he reminisces about her, it always seems to circle back to sex. Cuddling with her? Josh describes his penis rubbing against her. He also talks about how he misses what she would do for him, like cooking him meals.
In that same stream, when he's talking about bukakes, he said "why would I watch another guy get his dick sucked while I'm in a dry spell" while he pouts. He's got this weird sexual ownership over her when he's constantly reminding people that he had her first and all these other guys are getting his sloppy seconds.
I think him ranting about other guys is his "nice guy" mentality that he's had ever since his high school days. Either because he's jealous of other guys being able to talk to girls or get their attention or he assumes other guys are assholes who treat woman badly compared to him, because he thinks he's a great guy so it must be true. Thus showing his lack of self awareness. Thanks for reading my doctorate dissertation on boglism
