I do not need the sacrament of the orders in order to know that nudity is bad.
Every pagan knows this. Even morons know this.
Many Many moslems and prots know that the Church teaches EENS, and yet, many catholics (!) go to CA forums or EWTN asking whether there is such a dogma or not!
and Many Many prots, moslems, Jєωs and atheists, know that the Church teaches the objective superiority of celibacy over marriage, while some Trads (!) don't know! even some priests (!) are ignorant.

I do not need any authority to say black is black and white is white.
