Most of Somov's work you can fine online dates to his Paris period. (Door Open into a Garden, 1934, and Portrait of a Lady, 1936)
Unfortunately, I still have no romance with anyone - flirting is, perhaps, very light. But I'm tired of being without romance - it's time, otherwise life goes away and youth, and it becomes scary. I am terribly sorry that my character is heavy, boring, gloomy. I would like to be cheerful, light, so that everything is knee-deep, amorous and rip-off. Only such people have fun, interesting and not scared to live!
In Paris he struck up an intense friendship with a young Russian model, Methodiy Lukyanov. Looking at these pictures you have to think that this was a homoerotic relationship in some sense, but I can't find anyone who says outright that they were lovers or that Somov was gay, and Parisian artists of the 1920s were not shy about such things. So perhaps it remained Platonic, or perhaps Somov was just a very private man. Lukyanov died of tuberculosis in 1931, and Somov was bereft. But eventually he met another handsome young Russian man, Boris Mikhailovich Snejkovsk, of whom he also did erotic portraits; wikipedia tells us that "the exact nature of their relationship is unknown."
