I was the same way, but my b/f was supportive and talked me thru it as far as do this or dont do that.
Plus.. oral doesn't always have to be an ender... you could always just use it as a form of foreplay... thats how I usually use it.
Then you aren't "finishing" him off... so no fear of cum in the mouth.
Or... tell him to let you know when he is close... and move your mouth away and finish him w/ your hand.
