I'm confident that you enjoyed your 300 lb. Rush Limbaugh analogy. And, no, I wouldn't be sexually attracted.
But I think you're being too hard on yourself, perhaps inadvertantly. The analogy you need to consider for your H is that he woke up one morning and said, "Because you look like Angelina Jolie and not like Jennifer Anniston, I'm not sexually attracted to you enough to have sex 3 times a week and like it." (Kind of like Brad Pitt in reverse.)
IMO, this is NOT about your H's inability to step up to the plate sexually. It's about his unwillingness to practice. Incompatability may be innate in the beginning, but it only continues because of inflexibility.
