I am 5'3, 140 pounds, 36 D's. As much as I have a love/hate relationship with my breasts, they can definitely be really fun during sex (unless I'm on top and they do that weird pendulum thing, you know what I'm talking about ladies?). I also feel like they help in giving the illusion that I'm thinner than I am. I just wish they were a little perkier. I guess gravity is the real issue here.
