I think if there’s a true love the lovers will do whatever it takes to please each other because that is the biggest pleasure to please your love ones . As long as no harm.

If you know people well enough to really talk to them you find that many times things like this are what led to their divorce. Other ways of "working it out" just don't seem to work very well. Then you divorce and are secretly sorry. It's like saying you both used to have ice cream all the time and then, no more deserts.
I don't mean this as a drug reference.

Noone told me we have fetish brothels in Australia!
ahh, always the last to know.
This is a common scenario, very common if you allow a number of years.
Have been in this situation, a very kinky lady introduced me into lots of fun stuff, then she lost her libido, frequency of sex diminished all excitement lost and I was blamed for my continuing libido. She went nuts and relationship ended. We found out later that she had a reaction to medication that killed libido and effected her mentally. Did not find out for about 6 years, mean time I lost my house and she lost her kids.
