Within the world of social nudity, there are occasions when some activities and events may be clothing optional as opposed to strictly naturist/nudist. In other words, mixed company, both clothed and nude. Depending on the situation, these may vary in attendance and frequency. As a nude novice, it's important to be aware and for some, to prepare, mentally, at least, ahead of time.
Some men new to social nudism may possibly have a discomfort with being naked in the company of others who are wearing clothes, even if they are shirtless or in underwear. This is understandable given the different backgrounds in which some were raised. Persons who are taught from an early age that being nude in front of others is evil, nasty or a sin perhaps experience anxiety or unease in this type of environment. Actually, the same is also true for some veteran social nudists. Values, attitudes and beliefs instilled in us since childhood are often difficult to overcome.
It's important to know the reason why clothing optional or mixed company situations can occur. Some social nudist groups hold these periodically as a means of introducing other same gender loving men to the nudist life. Members are permitted to invite acquaintances and friends who are curious about naturism/nudism and hosting a social opportunity for them to meet gay nudists and undress to their comfort level allows them to experience and relax in a nakedness atmosphere. Another reason for a clothing optional gathering is a joint event co-hosted with another group that isn't nudecentric. Regardless of the reasons, such mixers are held and present chances for the two, nude and textile, to intermingle.
