How does this deity stand in terms of gender and sexuality? (historical and/or UPG)

The most common belief of Hecate is that she was a virgin goddess and was young and feminine.  Her are mostly depicted as a young woman or group of women.

Below you can see that the face appears to be young and the clothing is typically that worn by feminine women.

My experiences with Hecate have been as a single deity.  I've never had a real male figure in my practice and while working with her I've not been drawn to any particular God figure.
