Transsexual is a dated term. Also, "just be a femboy" is kinda bad if you have dysphoria and hate seeing your body slowly turn hairier, seeing your face turned manlier, seeing your butt get smaller. Hence, hrt exists and lots of people take it. But hrt gives tits, which means you can't "just be a femboy" cuz you'll always just be a tranny at that point. No point pretending not to be.
Even if you did "just be a femboy", with or without hrt, you'll always be perceived as a tranny. Most trannies have never gotten surgery for context, so having a dick won't change perception.
