Penis size does count, but not in the way you'd think. In fact, having a penis that's too long is more likely to cause your partner more pain than pleasure.

The average penis length is around 13 and 15cm when erect but even while many men might fall into this very normal size bracket, feelings of inadequacy can lead them to seek penis enlargement. In some cultures in south east Asia, a fear of penis shrinkage has lead to a booming market in penis enlargement remedies. Western culture is not far off with its fear of being found too small also encouraging a booming penis enlargement industry, but sadly, such treatments are largely ineffective and can do more harm than good.

The size of the penis is believed to be largely genetically determined, but some believe that environmental factors, such as pollution and diet, may play some role too. Exposure to specific chemicals (both synthetic and natural) has been found to disrupt genital development in both male and female foetuses in the womb, which is partly where this assumption is based.

Did you know that a man whose penis measures around seven centimetres when erect, but which functions normally, has what is medically known as a micropenis. It occurs in 0.6 percent of male population in the United Kingdom and is usually diagnosed and treated using hormonal treatment during a boy's youth.

With all this hullaballoo surrounding how long the male appendage is, it's small wonder that few have thought to consider just how sturdy its girth is, but this is what makes all the difference to how much pleasure a woman (and a man) can have during penetrative sex.  

A shorter, wider penis is more likely to stimulate a vaginal orgasm in your partner because it places pressure around the vaginal opening - an area that's full of sensitive nerve endings. It also offers more stimulation to the perineum and even gives the clitoris and labia a little bit of action.

If you have a longer, thinner penis then you're faced with the challenge of giving your partner the stimulation she might need to orgasm vaginally. Try grinding in circles once you're inside her to stimulate all areas in her vaginal canal.

While size might matter, it's certainly not the absolute law of great sex. Get working with what you've got and you'll be surprised to find you and your partner enjoying yourselves thoroughly.
