Stick a hose up your butt, and SLOWLY turn on the water.
There IS no safe way to inflate yourself. HIGHLY dangerous. No. Don't do that.
If you mean getting a boner then masturabte or think about sex.
Blowfish/pufferfish inflate with water when underwater, but inflate with air when removed from that environment.
Inflating yourself without water or an air pump is not physically possible for a living organism, as human bodies do not have the ability to inflate like a balloon. However, if you're referring to inflating an inflatable object, you could use your breath to blow air into it. Alternatively, you could create a vacuum to draw air into the object if it has a one-way valve. Always ensure safety when attempting to inflate anything.
To inflate with water, you can use water inflatables such as water balloons, water toys, or inflatable swimming pools. By connecting a water source, such as a hose, to the inflatables and filling them with water, you can achieve the desired inflation. Additionally, water pressure can also be used to inflate certain water devices.

You can inflate a balloon without air by using a different gas, such as helium, which is often used for party balloons. Alternatively, you can use a manual or electric pump to inflate the balloon with a liquid, such as water, which will evaporate and create gas inside the balloon.
