I can feel my dilator full depth in my vagina, and the area around it has touch sensitivity. My clitoris is not a "hot button" issue, but the rubbing sensation which is strong on the underside of my prostate does result in an "ejaculation" fluid release IF it let it happen that way. Self touch of the various parts does make the room light up a bit so to speak, but that is inside the vulva and not the vagina. For most cis women, this is the area they are most sensitive in as well. In short, I have more vaginal feeling than a cis woman, but close to the vulvar sensations of one. I can do an "O" if I want to, but dilation has to be done even if I have a headache or related and don't give a D about O.
