Many men remain dissatisfied with their penile size and comparisons in locker rooms and other such places are legendary, fuelling uncertainty and dissatisfaction. Somehow they feel that a smaller penis detracts from their value as a man. Briefly, the penis is composed of erectile tissue which consists of the corpora cavernosa and spongiosum. These are surrounded by a sheath of muscle. When the penis is flaccid these consist of spongy spaces that fill with blood when the penis becomes erect.
Many men worry about penile size.
It appears that the media had a great deal to do with creating unrealistic expectation of size. Actually its not what you have but what you do with it. It is often found in younger, anxious and sexually less experienced men. A new partner or long abstinence can also cause ejaculation to occur before it is desired causing anxiety and upset. Premature ejaculation is one of the sexual problems that is potentially easy to remedy.
