"Poke her in the eye with it" You are a rascal. I had a radical prostatectomy many years ago, and the surgeon was careful with the important nerves. A few weeks later, with the help of my friend, I achieved a modest erection. That capability grew quickly and continued for more than 10 years, until radiation therapy scorched my urethra and bladder and introduced incontinence, which made intercourse unpleasant. Together, we found a different and very successful alternative, which helped us fall in love a second time. Whether you achieve eyepoke capability or take another approach, I think this is a great opportunity for you and your wife, and I wish you the very best.
