Female led relationships discussion

A small thought that’s been on my mind lately: insecurity. I’m a Domme, so is it even reasonable for me to have these feelings about certain matters? This isn’t really about trust; the question is whether someone expected to be the alpha can think this way too. Is it alright to feel insecure sometimes, particularly regarding others who catch your beloved’s eye? I don’t think I’ve seen the word insecurity used much here. Also, I’m not saying I lack trust in my sub. My mind just drifts occasionally, wondering if I can truly be strong for both of us. LP
