Actually your first response was very helpful because it made me think my H was probably somewhat confused by my request.
As to the question of what's in it for him, I know he likes novel sorts of visual images so I thought he might enjoy seeing me hanging upside down naked. Also once he's actually aroused into sex mode, he likes "doing" me and knows from experience that if he did something like that for me, I would certainly follow up by giving him head.
It might just be too complicated. Probably what I should aim for to get that sensation is maybe doing it in a swing sometime.
Really my H would probably be "game" for just about anything I suggested once I've managed to get him in bed.I just don't understand why it's so hard to get him there when we usually have such a good time. I also don't understand why some of the things I do or suggest don't help him remember how much fun we can have. I sincerely doubt that I am deluding myself about how much he enjoys the actual experience once he's into it. He flushes, moans, takes the Lord's name in vain etc. and afterwards he'll say things like "Whew, that was fantastic!" He's not that good of an actor and not courteous enough to fake it anyways.
