Jadzia Dax joked that Trills don't look for romance the way
Humans do. Joined Trills consider it quite a nuisance and view it as a weakness of the young. While hosts may have romantic feelings as often as any other sentient species, symbionts try to live on a higher, more spiritual plane and try to rise above those sorts of temptations. (

A Man Alone")
Regarding how Trill society viewed romance and sexuality, Jadzia Dax actress Terry Farrell commented, "The Trill try to rise above such things. Sex is meant for procreation,
not for enjoyment.
" (The Official Star Trek: Deep Space Nine Magazine issue 2, p. 57)
Trill law forbids
reassociation between subsequent hosts of joined persons, whose symbionts were romantically involved in their previous hosts, and the people who the previous hosts were romantically involved with. This is because the main purpose of the transfer of symbionts is to experience new things in life. Trills who are found guilty of reassociation are expelled from Trill society, meaning that their symbionts die with their current host. (
DS9: "
Rejoined") Beyond the illegality of it, Trills almost universally view reassociation as a cultural taboo, but the degree to which they follow it is up to the individual. Some Trill take it so far as to not associate with any of their previous hosts' friends, family and colleagues, beyond the rare chance encounter. Others have a very narrow interpretation, and freely associate with the friends and acquaintances of their previous hosts & symbionts, avoiding only those with whom their previous hosts were intimately involved.
