Not to be too crass, but I have always wondered. I am good at giving oral to women but I have never enjoyed it for myself. I enjoy it because of the reaction I get and because I like making the woman happy. But it doesn't do anything for me in and of itself.
Do you like to suck cock for HIM? Or do you like it on its own merits? Perhaps a better way of putting it is: if you see a nice looking dick in a gallery pic do you ever say to your self "boy, I'd love to suck that thing" without any thought to the guy to whom it is attached?
Funny, we're rather parallel: I really enjoying giving, but not all that excited about getting oral.
In fact, I think guys sometimes think they *have* to give oral because allegedly "all" women really like it if done well. Frankly, even when it's technically very good, I really am not fond about it. By the same token, I have heard of some men, like yourself, who also aren't all that crazy about getting oral, even if it is good. A couple of times, I've had my ex's tell me that they are the best, etc., etc. and that they could convince me that it's just about getting a better partner, etc. Granted, at least once they proved they had an amazing technique, but I still really don't desire oral like stereotypes.
Not incidentally, a few of the other women who've responded thus far have indicated that when they give BJ, it really matters to them <b>who</b> they are doing it for (their husband, loved one, etc.). Me, I enjoy getting it somewhat more if it is with someone I'm really close with, but even so, it's not my favorite. Simply put, I prefer an average fuck to a great suck any day of the week.
Now, in terms of me giving head: I love doing it partly because I have a chance to really concentrate on cock and balls. Usually this is also the time when a man will be relatively passive (relaxed, lying down, etc.) and lets me just have fun on my own with his body: he lets me play with his toys on my terms and I love having it in my hands, mouth, as well as quite an eyeful.

Cock and balls are awe-inspiring, beautiful, and delicious and I get to play with his toys as long as I want at least up until he blows.
With all this said, I always wonder if I'm doing it "good enough." I've never had complaints (and have received at least a couple of comments that indicate I'm above average at least), but I know that it's always possible to do better. Each man is different and different things can have different (stronger, varied) responses.
Edit because I forgot to address whether it's just cock, or about HIM: it is definitely about the man himself and that he's sharing his body with me. I may see a nice cock or body somewhere, but it's not more than momentary appreciation at best. I'm not attracted by the body itself, but by the man HIMself.
