Sex in your house with someone from outside of your household is set to become illegal tomorrow. The government is introducing new lockdown measures that prevent people from socialising (or gathering) with one person from outside of their household in a private space.
Up until now the person visiting a house for sex would have been the one in breach of the measures. But now both people would be able to be prosecuted under the law with a bill called Amendment Regulations being introduced in Parliament tomorrow.
For those couples looking for a workaround, having sex in a public place is already illegal. The new legislation explicitly bans being inside the house in a gathering of more than one person without a reasonable excuse.
