'Licking someone out' sounds like something that the kids at school used to say, and is very much teenspeak.
I used to know a woman who regaled us with the horror tale of a boyfriend she had for a couple of months. (They were both mid 20's.) He encouraged her to 'go down' on him, and kept on at her to carry on for 15 minutes. She then said 'me next?'
He said 'oh no, I'm not into that.' 
Priceless.
She tolerated him for just a few weeks, but not til she had had sex with him 4 or 5 times. Each and every time, he requested the BJ, then sucked her nipples for 5 minutes, then stuck his penis in her vagina, huffed and puffed for 2 minutes and then shot his load.
Absolutely nothing in it for her at all, except having her nipples chewed for 5 minutes.
So if I had a man like this who was refusing to give me oral, I would definitely bin him. If he gave me pleasure in other ways, (and gave as much as I gave him,) and had lots of wonderful qualities, then no, it probably wouldn't be a deal breaker for me.
On a final note - to the poster 'anon1987; I get why the clit (area) may be classed as bristly if someone has shaved recently, or it has hair around it, but why the F is it 'discharged? '
