What does "one goose, two blacks and three purples" mean? How to understand?

Wild geese have crimson or reddish penises. Two black is a light black penis. Sanzi is the best penis in purple. Especially the black penis, gives women a particularly strong impression. On the contrary, a white penis, no matter how weighty, still makes people feel blistered and has no strong impression. Maybe it's a little thinner and shorter, but black gives people a sense of being lean and stimulates women's expectations. It can be said that from the visual point of view, the dark penis has occupied a very favorable position before it is actually used. The reason why the penis is black is mainly caused by melanin precipitation. The more sexual intercourse, the more intense the stimulation to penis skin, and the more melanin precipitation. In fact, melanin makes the skin stronger and is beneficial to the endurance of the penis. There is a reason why the black penis satisfies experienced women. But isn't there a more convenient way to blacken the penis than to do it a few times more? I suggest sunbathing on the penis. In addition to going to the seaside and mountains, you can also take off your pants and dry your penis on the roof where others can't see you when the weather is good. Just like sunbathing at the seaside, melanin will precipitate on the skin of the penis, creating a pair of black and thin penises. However, don't stay in the sun for too long to avoid dermatitis that is not suitable for sunlight. It's not like the back or arms here. Inflammation is troublesome. In addition, ultraviolet rays can easily cause skin cancer. In order to avoid sunburn, you can use sunscreen, sunscreen milk and other skin care products. It's like climbing stairs. You must not be anxious. You must exercise slowly.
