How To Get Your Ex Back!!!

I love giving my boyfriend oral sex because he likes it and thinks I’m good at it. I can deep throat about 4 times before I feel like I’m gonna throw up. Is there a way to like “train” yourself to not want to throw up? My eyes get all teary. I really wanna master it, he really likes it.
I forgot:
He’s 7 inches, I can take about 5?

when u brush your teeth, brush your tongue way in the back too. it takes time but its only mind over matter. dont give head on a full stomach. lol.
