Peyronies Treatment

I am 67 yo with chronic stage Peyronies which presents as a significant (60°?) upward curve during Viagra induced erections. Less pronounced with non Viagra erections but more difficult to achieve and maintain without meds. Causes painful intercourse with wife but as she is several years older than I, a straight erection would most likely cause pain as well so we use other options. Fortunately, I have zero pain and orgasms are still attainable and enjoyable for us both. Has anyone else dealt with Peyronies successfully and if so, what methods did you use? I’ve read several online comments from men who have used Xiaflex but that seems to provide 50% improvement if any.
