The question that I am asked the most has got to do with the size of the penis, most men have this notion that having a bigger sized 
male organ will make them better lovers and satisfy their female partner. The problem is that the vast majority of men who want to increase the size of their penis think that their size is below average, when in-fact most of them are at average or above. This is a major area of concern for them and causes a lot of unnecessary stress.
Here are the facts; an average erect penis size is about 5 inches long and 2 to 3 inches wide and is more than enough to satisfy their female partners. The truth is, that how you treat your partner emotionally and physically in bed is far more important than the size of your penis. This means that you need to work on your love making techniques instead of wondering if you are big enough.
Talk to your partner openly about what she likes and dislikes in bed and then make the extra effort to concentrate on the things she enjoys in bed and stay away from the things she is not comfortable with. How you treat your partner before intimacy is as important as during it.
Make her feel special and see the change in the intensity and satisfaction that you both feel during your next intimate session.
So stop obsessing about your size ( you are probably big enough) and start focusing on the more important things that will improve your relationship not only in bed but also outside of it.
As a side note, if you still feel that your size is below average and that you have to increase the size of your penis, then I suggest you talk to your doctor or a sex specialist so that you can learn about the implications, side effects and the effectiveness of the type of method you want to use for increasing the size of your male organ. Do this before you try any type of treatment.
