I just found an old oil lamp while cleaning out my parents' attic. It is warm to the touch regardless of the temperature of the surrounding environment, but it will not heat anything up (sealed it in a plastic bag, submerged in water, water temperature remained constant). It appears to be empty but every time I run my finger across it, it seems to vibrate as if an electrical current is running through it, and I can swear I hear it whispering to me in the night.

I'm pretty sure there is a genie in there.

I've already decided on my first two wishes, but I need some more information for my third one. Hence: do genies have penises? I'm not going to rub the lamp and check. That would be rude.
