Deltans 

Deltans are a humanoid species native to the planet Delta IV. All
Deltans are totally hairless, apart from eyelashes and eyebrows. Deltans
are also highly developed sexually, so much so that it is said that a
normal Terran would be unable to survive a sexual experience with a
Deltan. All Deltans wishing to join the Federation on mixed crew ships
must take an Oath of Celibacy. This is meant to prevent any unfortunate
incidents while on board any Starship. As well as being highly developed
sexually, they are also highly developed socially. 

Deltans mature at an older age than humans, undergoing a particularly
emotional  state, where they rely heavily on their empathic
relationships with their families.  Whilst this state is transitory, and
unlike Pon Farr, Deltans do not have to mate, they are highly sensitive
to others emotions and may need medical help or counselling.

Deltans tend to be open and gregarious by nature, and tend to be
Sensualists. This can also account for their proclivity towards
consensus and co-operation and being team players. They make excellent
teachers, athletes, scientists, engineers, Counsellors, Helm/Navigation
officers, and system specialists. 

Due to their overall good nature, they will wish to avoid conflicts
unless they see them in a constructive sense. Deltans can and will
defend themselves excellently with either bare hands or weapons. They
enjoy most sporting forms of combat, but do not make good Security
officers. 

Deltans generally live in group/line families and are intimately attuned
to each other and the psychological whole. This leads to having an
empathic dependency, so that Deltans serving on a mixed crew ship always
want at least one other Deltan on board. If this number is larger, they
prefer to be quartered together, commonly in modified quarters either
connected or communal in nature. 

Deltans also have a pheromone control system in their bodies which
allows them to produce pheromonal chemicals naturally. It is assumed
that this system is used during normal courtship rituals between
Deltans, but they can also produce other pheromones besides the erotic-
enhancing ones. 

Among the pheromonal abilities of a trained Deltan is the ability to
produce a pheromonal chemical which seems to reduce pain in most
humanoid races when used in tandem with their empathic abilities.
Deltans generally produce the pheromone associated with
sexual arousal on a day-to-day basis. They are usually considered very
attractive physically as well. This makes for bad psychological effects
on members of a mixed crew ship. Generally, Deltans do not serve on
mixed crew vessels in Starfleet. Those that do take the Oath of Celibacy
so as to not take advantage of any sexually immature species. Their Oath
of Celibacy only applies to species considered by them to be sexually
immature (which currently includes Terrans). 

Deltans serving with mixed race crews often chemically alter their
pheromones with a special chemical application, since it has been found
that suppressing the pheromone production causes illness and
psychological disorders amongst the race.
