Well, that's half the fun, experimenting to figure out what works best for both partners. :) I've had RA since childhood, so I've always had to approach *every* situation with an eye toward what's going to work and what won't. The key is to have a partner who's supportive and open to new ideas. There are ALWAYS ways to be intimate and give each other pleasure that don't include the *ahem* "traditional" routes. :) Approach it with an open mind, humor and love, and you're golden. Sorry for the pun. ;)
LOL....where did the phrase, "The Golden Years" come from, anyways? More like stainless steel and titanium....hips and knees, that is! UGH... Baby Boomers...boom we aren't babies anymore, except when we hurt. waawaaa
From one redhead to another...my mind is still that of a teenager but my body is ancient. LOL
It is hell this getting old isn't it? I can not believe that now we have to watch out for our joints and their positions while having sex! Not fun,eh?!
It's best not to rely on prednisone if you can avoid it. Long term use of it, even in small doses or occasional bursts, can CAUSE the very hip pain you're describing, because it causes something called avascular necrosis. Literally, the head of the femur dies and there's no treatment for it except hip replacement when the pain impacts your quality of life.
I'm probably answering too late for your appointment, I hope it went well.
Request her to take the top position. Lay there and relax for a change! :)
