aratahajimexy:The human male has a shaft-like appendage attached to his center. In M/F mating rituals, it (known as the penis) becomes engorged with blood and grows to accommodate a woman’s vaginal cavity. The penis delivers fluid to the woman’s egg, and in most cases, causes her to become pregnant with child. In any mating ritual (M/F or M/M), the penis is just all around fun to play with. Its growth is a sign that the male is aroused and ready for play. -- source link
