Bad gag reflex?

[Dargil]

First, a little anatomy. The part of the penis that needs the attention of your mouth is the head, AKA, the glans. In particular, once a penis is firmly erect, it is the "corona" (the ridge) and the "sulcus" (valley behind it) that are most sensitive. (This pic is not intended to be porn)

Corona and sulcus

So all you need do is pass the corona and sulcus through "kissing lips" to give it the pleasure it needs. You do not need the penis to touch your tongue to do it. Naturally you want to open your mouth enough to keep your teeth away.

Part your lips.

So your routine can be bobbing at just the head and stroking the shaft. When he gets close to orgasm (bucking, deep breathing), bob as fast as you can sustain for 5 minutes and begin stroking the shaft fast with a moderate grip.

Ask him to let you know he is going to cum several seconds before hand so you can lift your tongue tip toward the roof of your mouth. This will block the shot when it comes, preventing gagging. Remember to keep it there for several seconds, because he may have several squirts.

His orgasm may induce him to hold your head and want to drive into your mouth. This is instinct working and nothing personal. Just keep your hand on the shaft and if he drives, grip his penis to prevent it from going deep.

This should work.

I have the same problem, try using your tongue as kind of a barrier to the back of your throat.
Also being in 69 position makes deep throating easier, at least for me.
