Sex after prostate cancer
I am a pelvic floor physical therapist who treats men following a diagnosis of prostate cancer. I often ask this question of my patients and would welcome the responses of this group:
"At what point after the finale of your prostate cancer treatment did you attempt sex, either as a solo or partnered endeavor?"
I am guessing you are looking for responses from men who have had surgery rather than other modes of treatment.

Yes
No, I was looking for anyone who finished up radiation or proton therapy as well. Many of my patients undergo radiation and are then hesitant to return to sex thereafter. 
Hi Becca, my wife and I attempted sexual intercourse three months after my prostate cancer surgery. My penis was incredibly sensitive to the touch, and it didn’t take long to reach orgasm. However, it was painful at the end, and I leaked a little bit of urine. Over time, the pain and leakage disappeared. I’m now 4-years NED, and although my erections are not as spontaneous, they are almost as good as before. I’m happy to answer any questions. Gogs Gagnon Thanks for your candid response. Many guys report the same sensitivity and urinary leakage at first. And lots of them are reluctant to return to sex after their surgery. I'm so glad that your return to sexual function has been successful! My pleasure, Becca. At first diagnosis, I had no plans to talk about it. My mind immediately shutdown as I thought my life was over. I'm grateful for the love and support of my wife. She understood it was difficult for me to speak, so she suggested I write a journal. It opened up a new way to communicate. That helped open me up and from there I wrote a book! I'm proud to say that Prostate Cancer Foundation BC distributed a free copy to those newly diagnosed all across Canada. I never expected that to happen as I wrote the book for myself. A true labour of love. The name of the book is, Prostate Cancer Strikes: Navigating the Storm. If you would like a copy, please DM me, and I'd be honoured to gift you one.
I had 28 sessions of IMRT and 6 months of hormone therapy. I did not pause sexual activity at any time during or after treatment.Many men will not attempt sex during hormone treatment as there is no libido, but they really should give it a try with external stimulus (attempting to pleasure their partner works for many) to avoid atrophy. Intercourse does not require libido nor testosterone.
