What he stated and is doing is supposed to work right now. He's having fun, being honest and maybe he will find a new lifelong partner. That's what dating involves, finding the correct partner for your future. I'm not going to argue the sex part because his list, your list and my list are most likely completely different.
All I am saying is the "for now" doesn't matter, if you can't pass your first personal requirement in building a relationship. So, if it made you fear what he has concerning the future, you move on. I know I passed up on women because they smoked. I know women passed up on me because I didn't make enough money. I'm not a publicly affectionate guy so, some relationships ended for that reason. He'll pass up on women who don't have his zeal for sex. They may feel, as I did, they passed up on something special. That's irrelevant because we are each trying to find our particular happiness and compromise comes later. I'm not going to say it makes him worse until he does something awful. He changed his relationship priorities to include sex at the top.
Sorry, I think HD people can set that as their requirement and have meaningful relationships as well without deprivation.
