I didnt' find anything about Enyo being the angel of sexuality but I did find this:
Enyo (Greek: Ενυo, English translation: "warlike") was an ancient goddess of war, acting as a counterpart and companion to the war god Ares. She is also identified as his sister, and daughter of Zeus and Hera, in a role closely resembling that of Eris; with Homer (in particular) representing the two as the same goddess.

She is also connected to Bellona (Roman godess) whose original name is Duellona.
In Roman religion, goddess of war, identified with the Greek Enyo. Sometimes known as the sister or wife of Mars, she has also been identified with his female cult partner Nerio.
The name "Bellona" derived from the Latin word for "war" (bellum), and is directly related to the modern English word "belligerent" (lit., "war-waging"). In earlier times she was called Duellona, the name being derived from a more ancient word for "war".
Bellona was an Ancient Roman war goddess. She is believed to be one of the numinous gods of the Romans (without a particular mythology and possibly of Etruscan origin), and is supposed by many to have been the Romans' original war deity, predating the identification of Mars with Ares.
In art, she is portrayed with a helmet, sword, spear, and torch.
Bellona's festival was celebrated on June 3.
