Why do women get more excited when men have curved penises?
Preface
The more curved a man's penis, the more aroused a woman becomes—this statement sounds like a joke, yet it has been repeatedly mentioned online, sparking extensive discussion.

Is it just a joke, or is there some truth to it? From a sexual perspective, does the curvature of the penis truly provide different levels of stimulation? Is there any scientific basis for the claim that women prefer curved penises?
This article will take you on a journey to uncover the secrets behind penile curvature.

Primitive Era
In primitive society, sex was an instinctive behaviour and an integral part of survival competition.
At that time, humans had to face attacks from wild beasts, and sexual intercourse was extremely brief. The purpose of sexual intercourse was to pass on one's genes as quickly as possible.

In such an environment, the corona of the penis played an important role—during thrusting, men could use the everted edge of the corona to remove the semen of competitors from the vagina, helping themselves to better complete fertilisation.
Due to the urgency of time and the simplicity of movements, straight and rounded penises were more suitable for insertion and thrusting, giving straight penises an advantage in primitive sexual intercourse.

Conversely, penile curvature might cause a stuttering sensation during rapid insertion, hindering sperm entry into the cervix, and thus was evolutionarily disadvantageous.

Modern Sex: The More Curved the Penis, the More Women Love It
Today, sex is no longer just about reproduction. As sexual life becomes more free and longer-lasting, more people are beginning to focus on the pleasure and interaction that sex brings.

According to some studies and surveys, approximately 60% of women indicate that they prefer a slightly curved or upward-curving penis during sexual intercourse.
This structure makes it easier to contact the front wall of the vagina, particularly stimulating the G-spot, thereby enhancing pleasure.

The G-spot is located approximately 2–3 centimetres inside the vaginal opening on the front inner wall. An upward-curved penis forms a curved angle with this area during thrusting, creating continuous friction and triggering orgasm.
A completely straight penis may require manual techniques or position adjustments to achieve the same effect.

The debate over curved versus straight penises has a clear origin.
From a genetic perspective, approximately 68% of modern men have relatively straight penises, while 32% have naturally curved ones.
This disparity in proportions is likely the result of early human evolution, as straight penises offer a significant advantage in primitive sexual intercourse.

However, as sexual function has shifted toward ‘sensual experiences,’ curved penises have become more popular.
They offer more stimulation points, different angles of contact, and even greater flexibility in certain positions.

However, more curvature is not necessarily better—a natural upward curve of 10–20 degrees is considered the ‘golden angle.’
If the curvature exceeds 30 degrees, it may cause issues such as sexual pain or difficulty in penile curvature, which could indicate medical conditions like Peyronie's disease, requiring consultation with a professional doctor.

Penis Types: Which Type Are You?
In addition to curvature, penises can also be categorised as ‘blood penises’ or ‘flesh penises’:
- Blood Penis : Smaller when flaccid, with significant enlargement upon erection; common among Asian men;
- Fleshy penis : When not erect, it is close to an erect state, and does not change much when erect. This type is more common among European and American men.
A simple criterion for determination is: erect length ÷ flaccid length ≥ 2, indicating a blood penis.
There is no superiority or inferiority between these two types; the key is how to align with one's own sexual rhythm.

Summary
From primitive society to today, the role of penis shape in sexual behaviour has also evolved.
In the early days, efficiency and reproduction were emphasised, while modern times place greater emphasis on pleasure and experience.

A slightly curved penis, especially one that curves upward, can sometimes better stimulate the female G-spot, leading to stronger sexual pleasure.
However, this does not mean that ‘curved is always better.’ Rather, everyone's body structure and sexual preferences are different, so compatibility is the key.
Whether your penis is straight or curved, whether it is a blood-filled penis or a fleshy penis, mastering the techniques is the core factor determining the quality of sexual intercourse.
