Penis size is a very personal thing to many. I have many experiences with this, and there is no single answer. For me, I have no problem with the size of my penis, but for others it is different. I have found that the more the better. Here are some facts about penis size: If you are a guy, you probably feel that your penis is small. This is a natural response to the body. You may have been born with small penis or you may have inherited it. Most men, when they have an erection, will have a little less than a 1 inch penis. The length of the penis is the same, or slightly shorter, in both genders. This means that most men can grow a little longer. If you have a larger penis than you think, you might consider a penile enlargement (PH) procedure to enlarge your penis. The penis is made up of two parts. The head (or head) is the very largest part. This is the part of the penis that is erect and can feel the penis in your hand. It is the size you should use when masturbating. It can be slightly longer or shorter, depending on what you are used to. It is usually between 1-2 inches long. This part is the most sensitive.
