Lyric discussion by doondawg 

I think this song is about Sam's love of women. The feminine ideal. Its more than just his lover or his mother. There is a lot of symbolism about love making and post-coital cuddling. Also there is a reference to milk on his lips---clearly his mother. The imagery about the waves and the moon are about femininity in general. The women he loves, not just one.
