So much so that physiological, psychological, and cultural change over the generations made them better fit this role, as those who couldn't take it didn't get the privilege of breeding to the next generation, or sometimes even living to see the next day.
To be overly reductive, they quite literally became made for sex. Ever willing, ever ready, and a inbreed instinctive reaction to sexually submit to anyone physically or intellectually superior to them (which they tend to do to most humans as they resemble the race the mage lord originally was at one point).
In a way this both aided and hindered the transition to earth and a life of freedom.
It helped greatly in goblin X human relations greatly, even if human women complained a bit at first about it.
It hindered in a few ways, from many goblin girls not really knowing what to do with themselves outside of sexual service, to misunderstanding about certain sexual taboos or laws around sex work. Different countries and cultures found different solutions but between the goblins being quite agreeable and most men finding goblin girls hard to totally resist all but the most regressive cultures and countries quickly found some sort of understanding.
Now that the goblin girls aren't slaves being forced to do much of anything and rather than disposable they are seen as valuable both to goblin men and human men alike, they have fully embraced the pleasures of sexuality and sexual service. Finding power in the erotic, in being desired, in being enjoyed.
There were some worries at first about things like std or a population explosion, but as it turned out long ago the evil mage lord thought of that, somehow making goblin pussy juice a universal cure all for sexually transmitted infections of all kinds. Also turns out female goblins can only breed with male goblins, so sex with humans won't lead to a population explosion.
So yeah, goblins in general are free, and goblin girls in particular are sexually "free".
