Hi There,
Is your concern about prostate removal due to post-surgery sex...???
Nerve-sparing surgery is an option for some (depending on the location of cancer). There are lots of options for enhancing performance after surgery. I was fortunate to have bi-lateral nerve sparing survery and my hydraulics work fine without pills or shots - though it took almost a year to 'get it up'. (My surgery was 2 1/2 years ago).
Dr. Stein at USC/Norris says that some docs believe that taking pills (viagra or cialis...) on a regular basis after surgery can help speed things along. Or a bi-mix or tri-mix shot of drugs into the penis can help.
I only took pills a couple of times. I also received one injection into the penis about 6 months after surgery, and that really seemed to jump-start my hydraulics.
The following link is to a very good online support group for men who have had prostate surgery - and deals specifically with sexual issues. Both men and women participate in the forum. You might want to check it out.
