Tips needed on how to give deep throat oral

Hi My boyfriend and I love the idea of deep throat but im unsure as to how you are able to achieve that. Any advice and tips needed please.

Cream

my guy is very large and thats the way he wants me to give him head. so i went to the store i got the tube of gum gel, this stuff nums the tooth or gum so it stops hurting. so i put this on a tooth brush and put it as far back into my throat as i can then i wait for about 30min. then when i put in my mouth i can swallow it past my gag valve and can take it all in and when he cums you don't even taste it cause its in your throat already, its a great way to beat his size.

Practice! & have a bucket ready.

If you know anything about the back of your throat you wil know hat even touching it with your fingertip will make you hurl. So , get a cucumber (nice big thick one) and ask HIM to show you how...see how he feels then! HAHHAH No but seriously. You need to take things gradually, don't let him take control in anyway - or you'll need that bucket.Don't go stright down with it, run the tip along the roof of your mouth to the soft patch at the back,don't poke, then lengthen your lips, and hay presto..its all the way in.
Best of luck
