I see it the same way I see giving a massage. My husband says my back hurts, I slept wrong, I have too much tension, whatever the cause he'd like a back massage. It's not sexual for me. It doesn't get me in the mood. I get no pleasure from it. To top it off I don't enjoy it. Do I want to spend 30 minutes making my hands a little sore? No, I'd rather not thanks. Do I like giving massages no I don't. But I DO enjoy the outcome of my husband feeling good, relaxed, happy, and less sore, so I give him a back massage.

Same can be said for a blow job. Do I want to spend 30 minutes of my time doing something that gives me no pleasure or joy, makes my jaw sore, my hands tired, etc? No and I don't HAVE to do it. But again, I know it will please my husband, make him feel better, more relaxed, less stress, make him feel loved, and intimate even if I get no sexual satisfaction from it.

You just really hate giving oral that's fine don't do oral. I don't like doing it but I do it to make my husband happy. My husband does things for me all the time he doesn't like doing, but does because it makes me happy.
