What do Women Think About Penis Size?

Erectile Dysfunction

Premature Ejaculation

The majority of men will at some point wonder how the size of their penis compares to their peers. This is a completely normal curiosity according to the millions of searches per month on the topic worldwide. 

Many men may have concerns over penis length, wondering if it’s smaller than it should be or large enough to satisfy a partner. This negatively affects men’s mental and sexual health as it often leads to anxiety and issues with self-esteem.

The importance of penis size has changed throughout the ages. For example, the ancient Greeks saw a small penis as a sign of intelligence and self-control and large penises as a sign of being dumb and driven by lust. Yet times change and most cultures now associate large penis sizes with being manly, symbolising strength, fertility and ability. This leads many men to believe that bigger is better and perhaps they have not made the cut.

The fear this generates in men is exploited by many organisations that try to manipulate men into using devices and pills to increase penis size with little evidence they actually work.

The anxiety surrounding penis size can lead to very real sexual dysfunctions such as erectile dysfunction (ED) and premature ejaculation (PE). Long term this leads to reduced sexual activity as anxiety around penis size takes over enjoyable aspects of their sex life.

ED and PE can lead to further anxiety about sexual performance, worsening self-esteem and sexual confidence leading to a cruel cycle of anxiety surrounding sex. It’s important if you are in this cycle you speak to a health professional about your options. There are treatments available for ED and PE until you can address the underlying anxiety.

What is the average penis size?

The most reliable data available for average size comes from a 2014 study that measured over 15 thousand men. In this study, it was found that:

  • The average flaccid penis length was 9.16cm (3.6 inches)
  • The average flaccid penis circumference (around the penis) was 9.31cm (3.66 inches)
  • The average erect penis length was 13.12cm (5.1 inches)
  • The average erect penis circumference (girth) was 11.66cm (4.6 inches)

These measurements of length and girth were taken by health professionals, not self-reported. Many studies have been conducted with self-reported results by men which often lead to an increased average length. It’s been suggested that when asked men will often embellish their responses, which is unsurprising given the stigma surrounding sizes.

How to measure a penis

Some men grow a significantly larger amount from flaccid to erect. This is where the term growers and showers come from. For accuracy, it is best to measure your penis while it is erect. 

It’s important to note that the length of your erect penis will vary depending on temperature, arousal level, and age. This normal as these factors can affect how much blood goes into the penis during an erection.

To measure penis length:

  • Use a tape measure and measure from the pubic bone to the tip of the penis on the top size looking down. 
  • Ensure the penis is at a right angle to the rest of your body.

To measure penis girth:

  • Use a tape measure and measure around the middle of the shaft of the penis until fitting.
  • Is my penis small?

    A question that is, unfortunately, a result of inflated ideas around erect penis size. Even if you fall under the average, medical research states that only men who have a  penis length when flaccid of less than 4cm or erect length of less than 7.5cm should be considered for penis enlargement procedures.

    What do women think about penis size?

    A study concluded that 85% of women were satisfied with their sexual partner’s penis size while the percentage of men satisfied with their own penis size was just 55%. It also found that men around the average size often felt more anxiety about size than those who were under the average.

    The study goes further to say penis size is a much lower priority for women when it comes to choosing a partner. Personality, attention to grooming, and emotional connection are rated much higher than penis size, particularly compared with the male perception of how they think size would affect women’s partner choice.

    What can I do about sexual anxiety?

    Erectile dysfunction (ED)

    If anxiety about penis size is resulting in ED, you should first speak to your doctor or a sex therapist. These professionals are the best equipped to address the underlying anxiety. This is the long term solution to the problem and should be the first treatment used. 

    The short term solution is the use of erectile dysfunction treatments to assist with gaining stronger erections until other factors are addressed. These medicines include:

    Premature ejaculation (PE)

    Concerns about size can lead to ejaculation too early into sex, known as PE. Again the first option should always be to consult your GP or sex therapist in order to address the underlying anxiety for long term management.

    The immediate solution, while working through the anxiety, could be using a PE treatment prescribed by our Online Doctor service. These treatments include:
