Am I making a mistake by not giving Sissy/crossdresser a chance?

As I'm looking for subs, I always passed the sissy/crossdresser type automatically without thinking (sorry 😞), my reasons being:
1. I only get turned on by striaght guys, wearing things typical guys would wear.
2. If I don't let my sub dress in feminine clothes during plays, it would probably upset them and for that reason I just won't be the ideal Domme for them.

Am I wrong? Or sissy /crossdresser just one of your roles, you are perfectly fine not dress up or act feminine during plays?
