Also. Legally I’d have to flash someone INTENDING for them to see. To cause distress.
here’s an example.
If I stood naked at my door, is it classed as public indecency?
Hello, so me and my partner have had a debate about whether it would class as public indecency or not. We aren’t planning on doing it fyi, just curious if so we were to answer the door and people saw us stood there naked but we were in our home, is it a criminal offence?
There is no offence specifically called "public indecency" in English law (and in this answer I assume you are talking about English or Welsh law; a different criminal law applies in Scotland, and another in Northern Ireland). We have a few close analogues which I'll discuss below.
The answer to your question is: probably not, depending on your intention. Nudism is not illegal per se in England and Wales.
The first is the offence of "exposure", under section 66 of the Sexual Offences Act 2003. This offence is committed when you:
• intentionally expose your genitals, and
• intend that someone will see them and be caused alarm or distress.
If you intentionally expose your genitals intending that someone will see them, but without intending to cause alarm or distress, then the offence is not complete. Essentially: this offence prohibits "flashing", but not nudism.
If you also intend that the person to whom you open the door will be caused alarm or distress, then the offence is complete.
Important to note is that the offence does not require you to derive sexual gratification from the exposure (though that is why most people do it), and also that this offence can occur in any place, public or private.
The second is the offence of "outraging public decency", under common law (meaning it's not actually written down in law, it's developed by the courts many many years ago and has just stuck around). This offence is committed when you:
• do an act which is of a lewd, obscene and disgusting nature, and which is capable of seriously offending the public's sense of decency;
• in a place where there is a real danger that members of the general public might witness it; and
• in a place and in circumstances where at least two other people could see the act in question, even if they don't
In this case, I don't think that merely "being naked" is lewd, obscene and disgusting. If you masturbated, for example, then that would probably qualify.
