When a man loves a woman and she loves him back, they want to eventually express that with their bodies. I don't know how you're familiar with the female form but they have a thing called a vagina, and it like a socket. And then, what happens is, like, the man will insert the penis inside that socket, and babies come out. Once you're in, it's over in 10 minutes. And then, if she really loves you, then you could do it again.
