So, as the title suggests, I would like to read up on books that you think have a good depiction of romantic relations. Ideally not romance novels though, I would like to learn about it on the side rather than it be the main focus. Also would prefer if the characters were not each other's preferences sexually, for example, a gay man and a straight man, lesbian woman and a gay man, etc. Basically, I would like to learn the importance of physical intimacy and how putting limitations on that affects a relation.
Thanks
