I have a programmer friend (26m) who make a lot of money but can't get a girlfriend. He has an above average face and exercises regularly, but his 5'7'' height and introvert personality keeps him lonely. He used to want a normal relationship untill some of his friends got married. He said that all of their wives got fat and cut their hairs short after they got married. Now, he wants to have sex untill he is 30 year old, then he will think about marriage.

He is roommate with a young escort now. He does all the work at home (cleaning, cooking, ...etc.) and pays the bills. She lets him have sex with her almost everyday. I told him it is ridiculous to do this much work only to have sex. Then he showed me her photo. She is a solid 10/10. He also told me that he was already doing all the work at home when he was living alone.

With a quick search on the internet, i found that this type of relationship is not uncommon. It looks like it may be a good deal for successfull but introverted men who can't get laid.
