Any tranny here?

Any tranny here who wants to be my friend? I am interested in how y'all body anatomy work like during sex change surgery does the dick get removed and artificial vagina is attached but how do you remove a vagina, a hole with a penis tho? and if possible can the penis get hard normally? I am so confused can a tranny help me with this doubt? And if artificial boobs are attached how do they attach it and what are they made with? Does it function like normal boobs except the lactating part? I am curious
