These can be divided into 2 types:
primary – when a woman has never had an orgasm
secondary – when a woman has had an orgasm in the past, but can't now
Some women do not need to have an orgasm to enjoy sex, but an inability to reach orgasm can be a problem for some women and their partners.
Reasons why a woman cannot have an orgasm can include:
fear or lack of knowledge about sex
being unable to "let go"
not enough effective stimulation
feeling depressed or stressed
previous traumatic sexual experience
Research is being done into certain health conditions that affect the blood and nerve supply to the clitoris to see whether this affects orgasm.
CBT therapy may help a woman overcome orgasm problems. It involves exploring her feelings about herself, sex, and her relationship.
What is an orgasm?
An orgasm is a feeling of intense pleasure that happens during sexual activity. It's sometimes called coming or climaxing. Most people can have orgasms.
What happens during an orgasm?
When you have an orgasm, your heart may beat faster and your breathing may change. If you have a vaginal or clitoral orgasm, an intense pleasurable release of sexual tension is accompanied by contractions of the genital muscles.
Some people may ejaculate when having a vaginal orgasm. A clear fluid spurts from glands close to the urethra during intense sexual excitement or during orgasm. The glands are called the Skene's glands.
You may be able to experience more than 1 orgasm shortly after the first if you continue to be stimulated.
