You may be advised to wait a few weeks until after radiotherapy before having sex. This is to allow any inflammation and side effects to settle. Ask your doctor or nurse for advice on this, as it can vary.
You may find that you don’t feel like having sex for a while. This may be because of ongoing side effects, anxiety, or how you feel about yourself sexually. You, and your partner if you have one, may need a period of time to adjust. It’s not unusual to feel nervous about having sex for the first time after pelvic radiotherapy, but it’s perfectly safe for both you and your partner.
If you have sexual difficulties that don’t improve, it’s important to let your cancer doctor and specialist nurse know. It can be difficult to talk about your sex life and any problems you’re having, but doctors and specialist nurses are used to dealing with intimate problems. They can often give you advice and support if things aren’t going well. Your hospital doctor or GP can refer you to a counsellor or sex therapist.
