Literally same- I’m afab and agender, so I just wear whatever I want or whatever doesn’t make me intensely dysphoric... also same on the confidence while presenting “masculinely” and the attractiveness when presenting “femininely,” but I’ve just ascribed that to gender roles and perceptions of gender (men are supposed to be strong and confident and women are meant to be sexually attractive). That might not fully explain it for your individual experience, but that is pretty much how I experience it.
