You also have to consider discretion when it comes to things like cleaning.
In my experience, the vast majority of electronic masturbators and sex machines are noticeably loud. What are your living circumstances and how discreet do you have to be with your sex toys? For example, do you need male masturbation toys which can be hidden away during the day or do you live alone so subtlety is not an issue? If you’re going to buy an electronic male masturbator or vibrating Fleshlight, consider how loud the vibrations/contractions are and whether they will be heard through the walls.
