The thing with getting head is
You don't know what good head is until you get good head
I had this same issue
Head felt great for 20 mins and nothing
Or at least I thought it felt great
Til the next shorty was able to make me cum at will
She could do it in 3 mins if she wanted to
So believe me
If you never came from head shorty ain't doing it right
If the girl is decent at it
Just think about all ya wild fantasies
Forget that it's her doing it
And if it's wifey that is bad at it, you gotta put in the time and work on her game, women got ego just as much as men. If she's bad at it she'll feel less inclined to do it and the vicious cycle will repeat itself -
"Did you like it?"
"I wasn't sure"
Just tell your chick what you like while she's doing it, once she gets good she'll start improvising and breaking out the new moves

Practice makes perfect, and if your girl ain't practicing on you the only thing I can say is she doesn't give a fukk about whether you're satisfied or not. There's not much better than chilling on the couch with your girl relaxing, palming her ass and her giving slow neck till you cum
