going down on him. . . ?!

i've been with my boyfriend for about 10 months and when it comes to all things oral, he's always keen to go down on me but i hardly go down on him.. he knows its cause im not that comfortable doing it , i do sometimes but not as much as he'd probably like and i do want to be able to please him more , but i feel like i don't know what i'm doing or i might be doing something wrong and i get too nervous cause i overthink a lot.

any helpful tips or tricks for head?

i know i could ask him and talk more about it yes i'm aware, but i thought i'd see if anyone here has anything to say :)
