Many people enjoy the sensation of being gagged, but because everyone's mouth is a different size and shape it can be tricky for some people to find a gag that truly keeps them from speaking or pushing it out. Inflatable gags are one way around this problem. They can be inflated to any size and they conform to the shape of the mouth they're in as they're blown up, making them a brilliant choice for the submissive who truly desires to have the use of their mouth restricted as much as possible. Most are made from latex or rubber, making them more durable and helping to protect them against being bitten.
Gagging a partner (or being the partner who is gagged) can be an erotic experience for many people - and ball gags are the most common type. They're an affordable and accessible way to experiment with gagging, and the aesthetics are iconic enough to add a little extra something to proceedings - especially when combined with bondage and fetish wear. Some people do find, however, that they're a little too easy to push out of their mouths; if you want an entirely incapacitating gag, penis or bite models can be more effective. As with all things, a little experimentation can go a long way!
Gags come in many shapes and sizes. Funnel gags are not amongst the most common types, but they're invaluable to people who are into a few specific kinks. The most obvious of these is water sports, as a funnel gag makes some parts of that kink easier to practice! Those involved in feedism and fat fetishism also sometimes enjoy using them as part of the weight gain aspects of their kink. If you'd like to experiment with funnel gags, make sure to buy quality and experiment first--you could choke a sub if you make a mistake, so do your research and practice with care.
