Upon reaching the age of legal sexual consent, the government issues each individual a box containing colored/patterned bands that must be worn when in public to indicate levels of implied consent.
Different colors and patterns are used based on sexual needs/wants/proclivities, willingness to be approached, preferred gender, age range, etc.
Examples:
Black band would indicate zero sexual consent/openness
White band would indicate free use for anyone
Pink band would indicate open for female approaches with implied consent
Light pink band would indicate open for female approaches with no implied consent
Blue and light blue bands indicate the same for the pinks but for male approaches
Purple/Light purple bands indicate the same for Bisexuals
Patterns would indicate fetishes/kinks and can be worn with any colored band
A pattern worn with a grey colored band would indicate no sex except for the advertised kink
Age ranges would be indicated by a colored clip attachment to the consent band
So someone looking for a spanking but no sex would wear a grey band and a spanking patterned band
A woman looking for sex with a male in his 40's and open for spanking, domination, and anal would wear a Blue consent band with the appropriate colored age clip attachment as well as 3 bands specifically patterned for spanking, domination, and anal.
A person looking to develop a relationship prior to consenting for sex would only wear the light colored bands to indicate no implied consent and may choose whether or not to wear fetish/kink pattern bands. Wearing the fetish/kink bands while wearing the light colored bands DOES NOT give consent but instead indicates interest in those areas when consent is implied in the future.
