One major change can be the orgasm experience. With many treatments changing your semen production it is common for people with penises to experience dry orgasms; whereby the feeling is still there but there is no ejaculation. This can feel very different from the experience prior treatment with many individuals finding the feeling of orgasm more intense. Talking about these changes with people in your support network such as partners, other cancer survivors and doctors can help you navigate this physical change.

Erectile problems can be another associated side effect of prostate cancer treatment. With so many treatments for performance-related problems identifying what may work for you through conversation and research is important. Common treatments include tablets, vacuum pumps, injections, testosterone therapy and sexual aids such as vibrators.
