First, a history lesson: angels, biblically speaking, are horny bastards. The entirety of the Book of Enoch is all about angels sleeping with human women. Angels in the Bible even have genders. Most tend to be men but there are various books that also include female angels. However, they are also spiritual beings with no physical body. Angels that slept with human women in the Book of Enoch weren’t supposed to because it was against their nature. Furthermore, the angels’ genders seem to not matter, as they have no need to breed, even with each other. Because it seemed unnecessary for angels to have genders or have sex, eventually a tradition developed that believed angels had no gender and did not have sex.
Supernatural, especially in the fourth and fifth seasons, draws heavily on these Biblical traditions, but seems like it can’t decide which one they want to go with.
So let’s talk about Supernatural’s angels!
