This is not about sexy romantic stuff, but real love, the others are outlets. Love is so powerful, it exhausts the physical body. In the usual vernacular we love many things or aspects of things, but what do we mean. I pose that it is impossible to know because the word means too many things.
I have found words stringed together expressed by, oh fooey!
I am in love. I am afraid to say that because of context but it is so much easier, and I just have to say so, though I do not want to say who until I decide how, and can be sure it will be understood.
