Pre transition I wasn't subjected to it so, I only ever knew it as it was applied to other people. It was gross and exploitative but not in a way that I personally experienced. There was a bit of detachment from that, I didn't properly recognize it for what it was because my own dysphoria and discomfort made me somewhat oblivious to it.
When I first transitioned the male gaze felt like some metric I had to compare myself to if I wanted to be accepted. I started to subtly invalidate myself by all the ways my body differed from what was expected of me as a woman. It became a source of constant self dismissal and a feeling that I didn't live up to expectations of womanhood, and therefore wouldn't be accepted as a woman.
After several years of hormones and then bottom surgery I started to gain confidence in myself and I started to notice a lot more the way men look at me. The experience has honestly sucked as much as it is validating. I know I look good, that I'm conventionally attractive. I'm uncomfortable in a lot of settings due to that. I'm good at hiding my discomfort and maintaining my confidence even when I'm being leered at. But nontheless it makes me feel gross a lot of the time. I'm a gay woman, so it also feels like a part of me is being consumed without my consent just by me passively existing somewhere. Like going to the grocery store and noticing the guy staring at you standing next to his wife. He should know the way him staring makes me feel but if he does know he doesnt care. The way people treat me is totally different too. People being genuinely very nice and happy to speak with me. It's made me understand in a personal way not just how passing is a privilege but being seen as desirable by men is too. I'm still young so my experiences are still growing. I want to be a mom someday and I think a lot about how my children will be subjected to this too.
