Here is my 2 cents. For me I enjoy providing for my wife and family. I like knowing that through my efforts they have life a little more comfortable than others. I do not mean to sound like a materialistic bastard, but I like taking care of the ones I love.

Sex is another place I like to take care of my wife. It would bother me slightly if another man made her moan and satisfied her sexually better than I did. I know that a bigger penis does not equate to more satisfaction, but if she did climax harder, louder, and stronger from a larger cock, then it would bother me. I do not think I am alone here.

Fortunately, I am her only lover.
