it all depends on the surgery/outcome. I am nearly 3 years post op, and my fiance who had dated 3 normal women before me summed it up as "I have to think about it to notice the differences, none of them bad."
The doctor I used takes the entirety of the glands, (all of it) for the clitoris and immediate area, none of it got cut off, nor did any of my old parts containing nerves. I was un circumcised and rarely masturbated or let myself get touched down there before, I was really sensitive and as a result of all things said still am. my whole vaginal area is sensitive, my clitoris is too sensitive for any but the genteelest tongue.
I want to sock anyone who does that natal versus neo argument because of this or that misconception between male and female anatomy. It is all due to how good the surgery and how sensitive you were before.
Oral sex does not hurt, infact it feels very good... but the problem is I cannot really enjoy it because of sensory overload. Some neo women think they are not sensitive enough, which is just like some natal women too.
I am with someone who is a big fan of giving oral so i am reminded often.
