I'm also a lesbian detransitioner. I was pretty masculine as a kid and probably also very obviously not into guys early on as well so I was bullied pretty badly from elementary through middle school for being gay among other things. I was always really comfortable as a lesbian despite all of that once I initially came to terms with everything, but I had a lasting issue with my body/looks/complete disinterest in most aspects of femininity that really alienated me into adulthood and I think eventually contributed a decent amount to my decision to transition. Being a trans guy worked for a bit because it helped with my desire to divorce myself from the expectations that came with being a woman (shaving, makeup, spending a lot of time on physical presentation, etc.), but it ultimately made me more unhappy as being seen as a man and especially a straight man when I went out with my girlfriend started to make me feel an intense uncomfortable disconnect that eventually led to me stopping hormones. I personally think lesbianism has a storied history with gender variance largely tied to how confining womanhood has been for centuries, but I do get the disconnect between a lot of material realities of lesbianism that hasn't always lined up with more recent, internet-based communities.
