No one should be forced to do something they don't want to do... How the heck is that enjoyable? If I were in that situation I wouldn't enjoy it if he wasn't completely comfortable with it. So sure, I'd "do without" if he didn't like to do it, and I'd expect the same respect back (although I don't see why I'd have any problems going down on him ). I'd probably feel like I was missing out but I'm not going to make someone do something for my own physical pleasure.

At the same time though, anyone in that situation that their partner won't give them a good lickin' (male or female) I do sympathise with you. If your partner is just being lazy or stubborn then I think they probably deserve a ban on you giving them pleasure they aren't willing to return.

Just on an end note... if all else fails (begging, groveling, etc.), it is Christmas. Try holding some Mistletoe up... It's tradition - not sure people are allowed to refuse then.
