It is believed that this romantic love letter was written August 9, 1846.
Gustave Flaubert to Louise Colet:-
"I embrace you, I kiss you. I feel wild. Were you here, I'd bite you; I long to do so - I, whom, women jeer at for my coldness - I, charitably supposed to be incapable of sex, so little have I indulged in it.
Yet, I feel within me now the appetites of wild beasts, the instincts of a love that is carnivorous, capable of tearing flesh to pieces. Is this love?
Perhaps it is the opposite. Perhaps in my case it's the heart that is impotent."
Flaubert says above that he was incapable of sex but he was a well known user of local prostitutes and suffered from a venereal disease for most of his life.
