I'm working through this very question with a therapist. I'm extremely jealous of women. But wait, it's only women who I think look good. I'm not jealous of women who don't. Why is that? Is the cause of this jealously ultimately sexual on some level? It could be.
So, we're working on my self-esteem and reducing jealousy. I'm also trying to become more fem physically and introducing some "fem" things like taking care of my nails, etc. I'll never be those hot, young things. But can I be a fem version of myself? Maybe. Or maybe I'm just David Bowie. But, instead of beating myself over the head, I decided to take the journey and see what it's all about. A guide is helpful here, get a therapist and unload all your feelings.
