Maybe it has to do with the fact that his Mother is dying, who knows. Or maybe he's got other things on his mind, suprisingly not everything is about sex.
Just a thought.
To love is to suffer. To avoid suffering, one must not love; but then one suffers from not loving. Therefore, to love is to suffer, not to love is to suffer, to suffer is to suffer. To be happy is to love; to be happy then is to suffer, but suffering makes one unhappy; therefore to be unhappy one must love or love to suffer or suffer from too much happiness. I hope you're getting this down.
