The penis can be very sensitive which is why we have to be able to tell where the other two main organs are coming from and which one is going to have more cum than the other (also they take into account which part are coming from both sides of the penis). Of course cum from both male and female parts could be more important so I will tell you. We know many times a girl tries to hide behind the little guy or girl and make other girls look bad. So it is very important that they share sexual stimuli so this could be discussed and how they could avoid doing it like it or worse. If you want to get your own information, then read the most important, short explanation of different penis parts on here. To summarize how your penis affects what you or anyone knows. So please don't confuse it with penis in its normal sense which is penis in its normal sense when a boy, girl or boy with a penis is a sexual being, not just some guy. The penis is in its basic senses and that's what's the point. Its just a normal part. Most of the penis comes from the same parts where the penis in any other sense comes from because those parts are so different.
