I suppose this comment should be on vanilla but I'll just put a pointer over to here. I wasn't aware of any sexual connotation whatsoever. I once lived with a dude in Xxxxxxx - he wasn't my flatmate, I was his! - who cured vanilla pods. It was one of his various moneymaking schemes. He said it was lucrative enough but it was difficult to get decent quality pods from farmers, i.e. ones that are properly mature yet not split. In the mornings I'd wake up to the heady aroma of the vanilla pods being sun dried in the lawn. If I was around in the afternoons I'd help to collect them and bring them inside, inhaling deeply all the way :-) I know the amount of care that goes into producing quality vanilla and I can never think of it as 'plain' or 'straightforward'. It's the very aroma of exotica, an aphrodisiac crafted of both jungle and labour.
Thanks, VO and John! Bilby, the word vanilla has a long history (in the gay community at least) of describing "plain" (i.e. non-kinky) sex. If your point was that vanilla sex can often be wonderful and so should not be disparaged, I agree.
“Daniel Bergner, 48, the divorced father of two teenage children, is what sexologists would call a straight, vanilla teleiophile. He is attracted to adults, that is, prefers the opposite sex and doesn’t shop for lovemaking accessories — clothespins, clamps, carabiners, rubber gloves — at Home Depot.�?
