Sexual Issues
Sexual issues are often experienced by people with MS. That's because sexual arousal begins in the central nervous system (CNS)—where MS strikes. If MS damages the nerve pathways to the sexual organs, sexual response—including arousal and orgasm—can be directly affected. Sexual problems may also stem from MS symptoms such as fatigue or spasticity. Psychological factors and mood changes may also play a role in sexual function.
Sexuality is an important part of life. If you are having sexual problems, please do not ignore them. Speak with your health care provider. It may be a difficult and embarrassing conversation, but it's worth it.
In women, symptoms include:
- Reduced sensation in the vaginal/clitoral area or painfully heightened sensation
- Vaginal dryness
- Trouble achieving orgasm
- Loss of desire or response
In men, symptoms include:
- Changes in arousal and response
- Difficulty achieving or maintaining an erection (by far the most common problem)
- Reduced sensation in the penis
- Difficulty achieving orgasm or ejaculation
- Loss of desire or response
Dealing with sexual problems
The key to a healthy sex life in any relationship is communication. Talk with your partner, as well as your health care provider. By exploring options and requesting information, you can maintain a satisfying sex life.
A variety of therapies treat sexual dysfunction. Men should speak with their health care providers about oral medications, injectable medications that increase blood flow in the penis, penile suppositories, inflatable devices, and implants.
Women can relieve vaginal dryness by using over-the-counter personal lubricants. Petroleum jelly should not be used because it is not water soluble and may cause infection.
Working together to find other ways to give and receive pleasure allows many couples to have satisfying sexual relationships. Couples can benefit from different means of sexual stimulation. The National Multiple Sclerosis Society (NMSS) suggests, for example, the use of a vibrator to help overcome impaired sensation. Abnormal sensations and spasms can often be controlled through the use of medication. If bladder problems exist, techniques such as reducing fluids 2 hours before intercourse and emptying the bladder prior to sexual activity are helpful.
