Can you train yourself to deep throat?

I wanna be everything and more for my husband. I’ve done anal, sucked his balls, done some crazy things etc.. but for the life of me I can’t deep throat!!!!!

The moment will be super hot and he’ll tell me to deep throat and I can’t and it just ends up making me embarrassed and like I’m not giving him what he wants.. it sucks :/

Any tips? Lol
