Fear of rejection. It's common to wonder if chronic pain makes you less desirable, but the longer you hold that fear the more difficult it will be to overcome. Talk openly with your partner about your fears, and encourage him or her to do the same.
Fear of pain. Your instinct is to avoid additional pain, and your partner wants to avoid hurting you. That's only natural, but try to reduce the stress and anxiety that come with your fear that intercourse will be painful. Left unaddressed, that fear can be a self-fulfilling prophecy.
Relaxation exercises may help reduce your anxiety. Exploring different ways to satisfy your partner, and experimenting with sexual positions that carry less risk of pain, may help both of you relax and enjoy intimate moments more.
Fear of failure. If you're concerned that you may not be able to become aroused or achieve an orgasm, consult your doctor. The pain you're experiencing could be the problem, overwhelming and blocking your sexual feelings. But sexual dysfunction can also be caused by self-image issues, depression, alcohol or medication.
All kinds of stress and anxiety can cause sexual dysfunction, so practice patience and understanding. It may help to talk with a professional, either a therapist or your doctor. If you think medication is affecting your sexual performance, consult your doctor before you stop taking the drug to avoid trading one problem for another.
