Exploring the fine line

Hello all, I am going to admit, quite shamelessly, that I am doing research. No, not for an academic paper, (though I wouldn't rule out doing one if I could get a scholarship) for a book of erotic stories. While I have explored the fine line, I wouldn't say I've strayed too far from the edge. I am curious as to what people enjoy about pain. What signifies that it has become unbearable if you have been bearing it right up until that moment? What happens, and do you think it happens in the mind or in the body, when pain turns to pleasure? And do people buy books of erotic stories? Do all erotic stories have to have copious amounts of sex? or can they have no sex at all? Are people interested in essays. I have started a photo essay of sensuality and nature. Sometimes when I go walking along the headland here, I walk home in a total state of arousal. I download the photos I have taken as I stand again in the places that felt inviting to me. Mmmmmmmakes my body want to dance and play and have scintillating sex. Hope to hear from you.
