in general, i'm all right with my outside parts. i don't feel a great deal of dysphoria linked to what i can see.
however, i have always had a huge paranoia about pregnancy, to the point of it being a common nightmare of mine. it helps that my partners have always been female, but the paranoia remains. it took several years and a great deal of guts to finally schedule a gyn. appointment just to check on things. i think i'd rather get rid of my inside parts and keep the chesticles, if i had to choose.
on the flip side, i also have no desire to have male parts, inside or out.
