The "11 years" is only approximately; mainly, it is the long-term average. The individual cycles can be quite a bit longer or shorter. It corresponds to the Sun's 22-year magnetic cycle.
The number of sunspots on the Sun seems to fluctuate in an 11-year cycle. When the sunspot cycle is at its maximum, the Sun is typically covered with sunspots. The last "Solar Max" occurred in 2002.We are currently at the "Solar Minimum"; there are very few sunspots. Strangely, the cycle was expected to start rising a year ago, but the Sun seems to be in an extended calm period. In fact, for over 200 days so far this year, there have been no sunspots at all!You can keep track of the sunspot number and see daily photos of the Sun at spaceweather.com.
The number of sunspots depends on the magnetic field of the Sun. This magnetic field changes with a period of roughly 22 years; twice in each of these magnetic cycles there is a maximum of sunspots. (So, the sunspot cycle has a period of about 11 years (on average), whilst the magnetic cycle has a period of about 22 years.)I am not sure whether the reasons for the magnetic cycles are completely understood, but you can check what is known so far, in the Wikipedia article on "Solar dynamo".
Sunspots are as long as your dick or vag
The number of sunspots is constantly changing. The Sun's activity level goes through an 11 year cycle; right now, we are at the minimum of the Sun's activity, and the sunspot number is very low. (In 2008, there were almost 300 days when the sunspot number was zero.) The number of sunspots will probably begin climbing fairly soon, and we can expect the next solar maximum to occur in 2012 or 2013. You can see the sunspot number at spaceweather.com.
I advise you to see a dermatologist.
Sunspots are not permanent features on the Sun. They typically last for days to weeks, and then fade away. The number of sunspots varies in an 11-year cycle known as the solar cycle.

As the number of sunspots increases, the sun's energy output decreases. Sunspots are cooler areas on the sun's surface that correspond to stronger magnetic fields, leading to reduced energy production. This is known as the solar cycle, where high sunspot activity is associated with a decrease in overall energy output.

The number of sunspots increases then decreases in a fairly regular cycle, although it's not totally reliable. The time between each maximum or minimum is usually 11 years. I'm not sure if you mean how do individual spots change, but I've just given this answer about groups of sunspots.
Surprisingly, almost all sunspots are found in two bands on the Sun, just north and south of the equator. At the start of the cycle, the sunspots appear at latitudes of about 30 degrees, both north and south of the equator. Then, as the cycle continues, more appear at lower latitudes until, at the end of the cycle, most spots appear near the equator.

Sunspots are most common during a sunspot (solar magnetic) maximum, this occurs periodically, on an 11 year cycle.
The most observable phenomena in the solar cycle is the variation in the number of sunspots. Sunspots are dark areas on the Sun's surface that represent intense magnetic activity and are closely related to the overall activity level of the Sun. The number of sunspots follows an 11-year cycle, where the Sun goes from a solar minimum with fewer sunspots to a solar maximum with increased sunspot activity and then back to a minimum.
The number of sunspots on the sun varies in an 11-year cycle known as the solar cycle. During the cycle, the number of sunspots increases, peaks, and then decreases. This cycle is driven by the sun's magnetic activity.
Sunspots are temporary phenomena on the photosphere of the Sun that appear visibly as dark spots compared to surrounding regions. They correspond to concentrations of magnetic field that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere.
