Do you feel guilty if you allow yourself to indulge in wanting?

For instance, I have been wanting an iPhone for a while and have been telling myself it’s ridiculous and unnecessary and that I didn’t need it. Then… I bought one. Don’t get me wrong, I like the thing (bordering on lurve), but I do sort of feel guilty for buying it because it’s not necessary for me to have.

Do any of you feel like this when you let yourself become overtaken by desire or want? My goal in life is to be completely content with my current situation and surroundings, so how can I do so if I’m wanting and desiring material objects and worse, giving in to those wants?
