The biggest destroyer of a relationzhip or selfworth is poor body image issues caused by what is deemed perfect, atractive or desired. Im a nudist and so are my kids. My wife is on occasion as well. I facilitate higherloveworkshops to improve people's self awareness and perception of thier own body and beliefs. As a nudist I feel freedom and exhilaration. Some people cant even get undressed without covering the mirrors.
If you know these people be patient and continue being yourself so they may be encouraged to engage.
An old friend of mine once said. "Being nude is the ultimate equaliser. Noone cares what you look like in fancy clothes, because you dont need them to feel special."
