first off....just make sure if you do anything to change yourself physically it is being done for you and not her. doing something for someone else, especially when its life changing like losing a lot of weight, will only lead to resentment. trust me, i tried it with smoking and it was the worst idea.

second, whats funny about sex is that the more you have it the more you want it and vice versa. having sex ups your libido and makes you want it even more so if youre continually not having it, that's going to make it easier to go without.

even when i was overweight by only 10 lbs or so i didnt want sex as much. i was drained and could notice a difference in my mental state as well as physical. so ive lost about 35 lbs and am right in the middle of my normal weight and feel much more sexually healthy.

it might be easier for you guys to lose the weight if you try it together. but also, she shouldnt be making comments to you if she, herself, if overweight. until she does something about her own condition she has no right to criticize you. and the penis enlargement thing....do they even do that? lol
