Hi, Snail, can you quote any versions of the family that can be definitely said to be a euphemism in this sense? Otherwise, to me it's just literal. On the other hand 'she opened the door in her nightie' is definitely a sexual double entendre. The old ones are the best!

Your 'Song of Solomon' seems to be full of symbolism, some of it erotic, but that doesn't mean our modern interpretations of the plot are.

Would that be perhaps 'foggy dew' in the second verse?
