Tbf, the lore behind Gwyndolin is vague in this respect.
The item descriptions all use male pronouns and his feminine appearance is the result of a ring he was forced to wear.
In Dark Souls 3, Gwyndolin seems to have abandoned said ring, because you find it in the location of Gwyndolin's Dark Souls 1 bossroom a significant distance away from where Aldrich devoured him. So it seems he does at least tries to present more masculine after Gwynn is no longer around.

Feminine appearance doesn't necessarily say anything about someone's gender anyway.
Oof, yeah in an ideal world that should go without saying.
