What medieval theologians debated whether angels are male or female?

Hildebrand, *Man, Woman, and the Meaning of Love* , § "Friendship Between Man & Woman", §§ "There are many spiritual differences between the sexes" claims: >In the Middle Ages the depth of this difference [between men and women] was totally understood, as evidenced by the interest in the question of whether the angels were also masculine and feminine. What medieval theologians discussed this question? St. Thomas's , John of St. Thomas's , and Súarez's treatises on angels don't appear to discuss it. I've [heard it claimed](https://www.youtube.com/watch?v=3gO0O7w5VBs) that our souls are male or female, yet St. Thomas denies this ([_Super Sent._, lib. 4 d. 25 q. 2 a. 1 qc. 1 arg. 3](http://www.corpusthomisticum.org/snp4024.html#19092) : "*Sed sexus non est in anima.* [But sex is not in the soul.]") and so does St. Ambrose ([_De Virginitate_ cap. 15](https://archive.org/stream/patrologiaecur16mign#page/152/mode/2up) : "*anima enim sexum non habet* [for the soul does not have a sex].").
