No, we give better head because we realize that genitals are actually remarkably similar. Clits are basically tiny dicks. Each has sensitive spots in similar areas. Practice on one can translate to another. Its not rocket science, its phallic science borne through watching a lot of wild surgery videos and analyzing post op results to determine nerve sensitivity :very-smart:.
Also hrt makes your tongue 3 feet long :shrug-outta-hecks:
I like to think about how the testicles exist in a sort of opening similar to the vagina except the sex bits fell out into a bag instead of going up inside (more? i guess?). What I don't understand is why the urethra forms inside the penis versus existing below the sex nob nerve cluster that is the clitoris. ¯_(ツ)_/¯
