Explain SMBC — the wiki for Saturday Morning Breakfast Cereal

This comic depicts a father sitting on the bed with his daughter, beginning "the sex talk." He tells her, "Sweetie, I think you're old enough for the sex talk." She responds, "Okay." But instead of actually explaining the facts of life, the father says, "So, I'm sending you to a deserted island in an undisclosed location." The caption below reads: "This is why mothers usually give girls the sex talk."

The humor centers on the stereotype of the overprotective father who would rather avoid the topic of his daughter's sexuality entirely. Rather than educate her, his instinct is to isolate her from any possibility of romantic or sexual contact. The punchline exaggerates this protective impulse to an absurd extreme -- banishment to a deserted island -- while the caption wryly acknowledges that this is precisely why fathers are typically not the ones to handle this conversation with their daughters.
