I am just now seeing this!
We are an interesting study in eating habits in married couples. He could eat a whole pizza and a case of beer and wake up tommorrow 5 pounds lighter. I eat the first slice of pizza and I gain 10lbs. Being with him, I have had an even harder time with my weight (a life long issue for me on more than 1 level

) because I see him eat so much junk I convince myself that 1 bite will not hurt. I have picked up his eating habits some and my weight shows it.
DH is the only skinny guy I have ever dated and among a very small handful of ones I have ever even found attractive. This is not the reason I like big men, but it never hurt that I looked smaller standing next to them, lol! I understand what the OP was saying though!
