Yes. You can bang anyone you desire in heaven, there are infinite dimensions, infinite people and infinite possibilities, all you must do is believe. You will live forever but you cannot really own the universe. The universe is for all as we are all one. You are the universe.
Which proves heaven is just in your mind. What if the chick you wanted to bang didn't want to bang you? How would that be heaven for her? It would be rape.
Alternate dimensions? So you are not really banging her, you are banging your vision of her. Which is just in your mind.
