Dang meds!
There is always a down side ~ always!!
Something about your post makes me think that you're the one on top usually, doing the work. Is that right? If so, maybe you should try changing things up a little bit. Have her be on top and pick the pace. You can hold her hips and watch her work for pleasure.
I would think that in itself could be exciting to you. And, as she gets close to orgasm, you could roll over on top of her and finish to bring you both there. Hopefully, it wouldn't take long for either of you to reach that point.
That's my advice. Best wishes to you both!
