My budget pretty much depends on the current finances at the time. If I had to estimate I would say that between $50-$150 is spent on sex related items a month. This includes lubes, cleaners,wipes, sexy clothing, toys and condoms(which has highest priority)

I do keep an eye out for good deals and try to make my budget stretch as far as possible. There have been some months where no orders were made, in those cases I either roll that money over to the next month to buy something more expensive.
