Vaginismus
Vaginismus is a condition which affects a woman's ability to have sexual intercourse, insert tampons and undergo gynaecological examinations. This is due to a conditioned muscle reflex in the PC muscle, they clamp shut making penetration either extremely painful or in many cases, impossible. The woman does not choose for this to happen; it is a learned reflex reaction. A comparison which is often made, is that of the eye shutting when an object comes towards it. This, like vaginismus is a reflex reaction designed to protect our bodies from pain. more...
A woman with vaginismus expects pain to come with penetration and so her mind automatically sends a signal to her PC muscles to clamp shut, thus making penetration either impossible or very painful. The severity of vaginismus varies from woman to woman.
The condtioned reflex creates a vicious circle for vaginismic women. For example, if a teenage girl is told that the first time she has sex it will be very painful, she may develop vaginismus because she expects pain. If she then attempts to have sexual intercourse, her muscles will spasm and clamp shut which will make sex painful. This then confirms her fear of pain as does each further attempt at intercourse. Every time the fear is confirmed, the brain is being "shown" that sex does hurt and that the reflex reaction of the PC muscles is needed. This is why it is important that if a woman suspects she has vaginismus, she stops attempting to have sexual intercourse. This does not mean women with vaginismus can not partake in other sexual activities, as long as penetration is avoided. It is a common misconception that these women do not want to have sex as a lot of the time, they desperately do.
There is no one reason that a woman may have vaginismus and in fact, there are a variety of factors that can contribute. These may be psychological or physiological and the treatment required will usually depend on the reason why the woman has the condition. Some examples of causes of vaginimus include sexual abuse, strict religious upbringing, being taught that sex is dirty or wrong or simply the fear of pain associated with penetration, and in particular, losing your virginity. These are just some of the reported reasons behind vaginismus and there are many, many more. It is a very personal condition and so each case must be looked at individually as causes and treatment can not be generalised to all women with vaginismus.
Most women who suffer from vaginismus do not realise they have it until they try to insert a tampon or have sex for the first time and so it may come as quite a shock to them. Whether they choose to treat the problem or not is entirely their choice and they should never be led to believe that vaginismus must be treated. It is not an illness or a dysfunction and therefore the only physical effect it will have on a woman is making penetration painful or impossible. It will not get worse or more serious if left untreated unless the woman is continuing to have sex/use tampons despite feeling pain on penetration.
Primary vaginismus
Primary vaginismus occurs when a woman has never been able to have sexual intercourse or achieve any other kind of penetration. It is commonly discovered in teenagers and women in their early twenties as this is when the majority of women will attempt to use tampons, have sexual intercourse or complete a pap smear for the first time. It can often be very confusing for a woman when she discovers she has vaginismus as we are led to believe that sex is something that comes naturally to us. It can be even more confusing if the woman does not know why she has the condition, as is true for many women.
