I think actions other then sexual, such as the ones you have mentioned are the real proof of love. Giving the last glass of milk. Washing the dishes for. Shining their shoes. Making them more comfortable, even if you are a little uncomfortable. Thinking of them first. These to me are great examples of the things we do when we love someone. Sex is great when you are in love with someone. But sex can also be great when you are not in love. I also feel that in a Love relationship sex is very important. But in a relationship if all you have is sex, you have nothing!
