I'm not sure what topicstarter meant and I guess we'll never know since he deleted. But it's obvious that with age our senses lose perception while experience grows and many things that were exiting before become ordinary or even boring. In the same time "giving a fuck" factor also lowers. Not for all people, but for many it just don't much matter anymore what others think.

Hence the trend among older people to go further in their sexual experiments and practices and being straightforward about them.
