wow!!! 5 times a day? Well no wonder she so tired!

seriously, I am a female, and I can tell you although some of us are very sexual in nature, our sex drive is nowhere near as high as a man. after about the first or second round at it, anything else more that I do is just to satify my partner. She may actually be just tired, nothing more. Maybe, she did it 5 times a day in the beginning, just to satisfy you and now, well, she's just tired. Now, I ask you, to be more sympathetic to what she may need. I am speaking as a woman, it would get real old if every time my boyfriend was near me he was constantly wanting sex. I doubt very seriously if your weight gain is a factor here. You have worn the poor girl out! You might have to actually try spending time with her and try not to pressure her. do some of the things that she likes to do, try more foreplay, pay more attention to her (above the belt). Women love attention and lots of it. This is going to take some time but trust me, it will work. You have to be patient.
