Trans women who want to get rid of their penis get shafted (pun intended) by circumcision as it reduces the amount of material for GRS.
That plus those who want to keep it have to deal with the same impacts as other penis owners. Perhaps even more so, as lack of T and atrophy are not assisted by the loss of the protective layer.
Most people don't really have a string opinion though, since you don't often find someone who experienced a sex life with a penis in both configurations.
