At the risk of sounding repetitious from some of the other posts I've made, I strongly agree and support what Mama Bluebird said about the need for the sphincter to heal.
This operation involves taking out the part of the urethral tube that goes through the prostate (duh!) and then sewing the free end of the tube back to a newly made bladder neck replacement. Since this tube is like a macaroni, you can imagine the careful stitching the doctor had to do.
Have patience. My doctor told me no sex of any kind for six weeks to allow this sphincter area to heal. If it tears, because of exuberant sex or the muscle contractions of orgasm, you could develop an internal leak. I had one anyway, without the sex, and had to have the catheter in for a month. You don't want to have the catheter put back in.
With the delicacy of this part of the surgery, it amazes me that more doctors don't tell their patients to cool it for six weeks. My doctor's nurse educator told me, quite to the contrary of Biker's doctor who said to have sex four times a week after the catheter came out, that if some miracle occurred, if God had given me an erection during that time (which she knew wouldn't happen), just to admire it, but NOT to use it. She gave me an Rx for 25 mg of Viagra to take once a day, but this was to provide a minimal amount of blood flow to continue, not to get it on.
