Absolutely nothing wrong with friends with benefits or casual sex or dating non exclusively etc as long as it is dicussed early on and mutually agreed upon. Then no one would be upset. And I think it’s important that we ask questions early on and don’t assume things. Because someone spends a lot of time with us or looks at us pleasantly it doesn’t necessarily mean they aren’t searching for someone else at the same time.

I agree with seesaw that if you want him for sex then just keep him strictly for casual sex.

But I also think if you want to continue seeing him for fun such as going on dates then I’d not sleep with him and I’d keep my options open.
