My wife and I are against it. It seems to me that only people with psychological problems agree to this. I am strongly against it and would never agree to it. I would never agree to such things being openly discussed. Can't we do without outside objects?

If both of us are interested and want to try it, then why not? You've probably never tried it if you say so. I, for example, like light BDSM. BDSM can be fun, it's just an experiment that both should be ready for. We decided to try it and got ourselves a leg speader bar. Now it's just variety and a chance to try something new, but we will definitely continue this theme.
