Lovecraft himself probably never much of a sex life ; according to his biographers, he had one unhappy marriage and spent most of his adult life living with an aunt. Poor Howie.
Then, of course, there was Charles Lutwidge Dodgson (1832-1898), better known as Lewis Carroll; mathematician, Anglican clergyman, author and photographer. He never married, and seemed to have had a difficult time in forming relationships with mature women, but he liked to be around young girls. There is a legend that he proposed marriage to Alice Liddell (the inspiration for Alice of “Alice’s Adventures in Wonderland”) when she was 11. He also liked to photograph pre-adolescent girls, nude or semi-nude, quite often in distinctly erotic poses; but this, by all accounts, was quite a common practise at the time - a naked child was supposed to be symbolic of innocence, or purity, or something.
