Yes, there are age restrictions when using a free discreet dating site. Most sites require users to be at least 18 years of age or older in order to join and use the site's services. This is to ensure that all members are of legal age and are able to make informed decisions about their online interactions. It also helps protect minors from being exposed to inappropriate materials or situations on the site. Some sites may have different rules for different countries so it is important to check the specific terms and conditions of your chosen discreet dating site before signing up.
