A lot of CD's and even TS who say nothing about it is sensual are just trying to "clean it up" for the GG's and to look wholesome. There is this theory among some TG that GG's have no turn-ons related to wearing anything.
God forbid you call yourself a TS and have some kind of turn-on relating to wearing something femme, that is the very definition of "not a true TS". Which is why some of the younger ones run around looking like an 80's hooker in a rock video.
At least CDs are quicker to admit there is an element of arousal.
I can imagine some older people may honestly not get aroused by near anything cause sex drive does diminish as you age but most of us are not older.
I did an extensive research about the age which masturbation stops for someone. Yes, I asked my dad if there was an age. He said, "If there is such an age, it isn't 70".
