Light bulb and my pussy

An interesting question came to my mind - will a light bulb glow if it is inserted into a pussy?? I found several suitable light bulbs and began trying them on. But they don't want to glow! I inserted them with one end and inserted them with the other end, and completely pushed them into myself... They don't want to glow anyway! Why?? What am I doing wrong? maybe I need to cum harder? Or lubricate the holes with sperm? We'll have to repeat the experiment!
