Most women prefer girth over length, and scientific studies prove it. A wider penis promotes greater clitoral stimulation, and length is far less significant. The vagina is actually relatively shallow, with an average of 4 inches of depth. Most of the sexual stimulation happens along and near the wall of the vagina, so if you want to have the maximum impact, girth is necessary.
You may have 9 inches of length dangling like a pendulum between your knees, but if the circumference is weak, then sex will not be enjoyable for a woman.
Sexologists and sexperts agree that girth is more vital than the length in the long run, and not so much of the length, unless it is just 2 inches when erect fully. Bigger penis girth gives both strength and consistency of the penis. When the penis is making its entry into the vagina, it hits wider area that hold sensitive nerve endings resulting in a much intense sensation for orgasm.
Additionally, the tighter it gets into the vaginal walls, the more pressure it has to stimulate the nerve endings. The vagina entrance simply stretches and adjust to the penis size, unless the penis is bigger than the head of a newly born baby.
Another fact why girth matters over length, majority of the sex sensitive nerve endings are found close to the vaginal entrance. The first 3 inches deep into the vaginal entrance wall considered the most sensitive area.
The survey found that 45 out of 50 women prefer girth to be sexually satisfying. Therefore, the survey concluded that the bigger the penis can fill the vaginal walls, the better sexual sensation it offer. Sadly, the survey did not gather data as to what sizes are preferred or can be considered to create less sensation.
When blood flow is at its best, the penis expands to its maximum girth and stiffness, but you may have already caused damage to your natural blood flow without even realizing it. Do you frequently masturbate? Or did you frequently masturbate as a teenager?
Frequent masturbation causes scar tissue and plaque accumulation along the penis, and that causes blood flow to become inhibited. But before you do anything else, you should definitely cut back on the masturbation, assuming that's still an issue.
