Sexuality after Prostate Cancer
Impotence, or not being able to maintain an erection to have sex, may be a problem after prostate cancer treatment. This may be temporary or permanent. If you are able to get an erection, you may be able to achieve orgasm. However, no semen will be ejaculated during orgasm. Some people call this dry orgasm.
Talk to your health care provider about erection problems. Treatments include, vacuum erection devices and medications given by injections (shots).
