Remember that decreased sense of sensation is not the same as decreased feelings for your partner. You can still be loving and giving to each other. Change positions to reduce direct pressure on the bladder. If you have an indwelling catheter, it can be taped out of the way in women, and men can fold it back over the penis, and cover both penis and catheter with a condom. If bowel incontinence is a concern, avoid intestinal stimulants such as meals or coffee before intercourse.
Sexual activity can occur in the shower.
Install a shower stool or chair to allow yourself to be more comfortable. Use pleasant soaps or body-gels, bathe together with your partner, and enjoy some intimate time under the warm running water. Some medications can affect your sexual wellness. Talk to your doctor about possible side effects of the medications you are taking. Have your doctor help you time the intake of your medicine in order to minimize side effects at the time of sexual activity.
