Is there anyplace outside my house that I can masturbate in front of people without getting into any legal trouble? Is this legal to do anywhere? Is it even legal to do in front of people that can see me through the window of my house?

You can go to mastubation parties. But actually like in a park or a mall then know. Now what you do in your house can vary by state. You can fuck and masturbate anywhere in your house or your property. But to masturbate for the entertainment of others can be seen as porn. But look at your local law. But my best advice get some friend together and masturbate.
