And now that I have your attention! :)
This is actually about communication. What is unspoken in love rather than anything spoken.
Its the communication in the quiet spaces in between talk and words, where we find some of the truest and deepest intimacies in our relationships. When the peaceful quiet between lovers is filled with gentle calm, comfortable communion, warm being - that is when you have a relationship worth fighting for during disagreements and misunderstandings.
and yes... sex is communication :) The ultimate form thereof really. We say a lot about ourselves in our expression of sex. When its about the one you adore and you simply have no other way of expressing your love for them except through the physical, [with or without words], it can be the most beautiful communication there is.
