Is it weird to self reference? (Patreon)

The argument of the importance of reference rages on, reference is without a doubt one of the best ways to draw, the fact that some artists can intuitively just remember what something looks like and draw it will always stun me.I'll admit-- and its not something I wanted to admit because I was made to feel bad about it back in the day-- I've used my self as reference for art.I've used my own breasts, my own facial expressions, poses, and even pictures of my own high heels for reference.But a while back a former friend told me there was nothing worse than people who self reference, that its egotistical. I didn't particularly buy it, their mentality that is, but it's stuck with me.So I want to ask you guys what you think, does self referencing make you egotistical? Or does is it just the quickest way to get pictures of the exact poses you like? Please lemme know what you think cuz I'm interested in hearing what your perspective is on it.
