I've been wondering about this a lot lately. Do you still get "butterflies in your stomach" excited when you bone your partner after boning them at least 2 years? Maybe not every time but at least 3 out of 10. I've had friends say they absolutely still feel excited to have sex with their partners while others have described it as a decrease in intensity. What have your experiences been?

ETA: Well after reading a bunch of your answers I think I can confirm my relationship is completely doomed.
