That's a default image that Apple has apparently tweaked. Pick your own from the available list of provided icons in your account settings here in the communities. Or upload your own image, as I and other responders here in this thread have done. This isn't from your system, Apple won't upload an image from your system without your permission. Or a cat picture, as seems common. And FWIW, inferring a person's gender or their preferences from an in-person meeting or from a photographic image—much less from a silhouette such as here—is fundamentally impossible.
