Both must be a giver and a reciever

Okay.

Not always the case in a gay relationship

I'm not sure if you mean this literally, if you are trying to express the concept of "symbiosis," or possibly "communication."

Other than that, I am not sure how that is relevant to the title of the thread as these things don't "fuel" the relationship so much as "conserve" or "allow for greater efficiency" that which is actually "fueling" a relationship.

Yeah, if you're giving her Regular Unleaded....


Why not give her Jet Fuel... you'll be so hungry for her, you can't stop, reciprocation will never even cross your mind... It's about that look on her face.....back when I as active 30 years ago I did anything and everything to get that incredible amazing look on her face.... legs squeezing hard, gritting teeth, tendons in her neck, hissing like a locomotive, jawbone muscles in knots, lips in a half sneer/smile, face turning darker and darker from the blood rushing to her head.... you get the picture.....

Golly Geee, I'd like to do that again, just once......
