Achillean (also known as Men Loving Men (MLM), Apollian and Chaeronean) refers to men or masculine-aligned person who is attracted to other men or men-aligned people. This attraction doesn't have to be exclusive, as the label is used in a way to unify all men who love other men such as gay (vincian) men, bisexual men, pansexual men, etc, promoting solidarity among men of all identities. Since achillean is an umbrella term, it is typically not used as an identity on it's own, however it can be if desired.
