This is a simplistic answer. Look at East Asian cultures to seem a much more sexual conservative environment. Try to delve into the why and it's complicated! As far as I can tell it boils down to marriage stability. Most people date to marry (any relationships that don't lead to marriage are viewed as a failure). Promiscuity leads to sexual insecurity as the less experiences partner fears not living up to the more experienced partners expectations. So this creates a strong downward pressure on everyone to not be promiscuous (and in small communities peer pressure is overwhelming) I can imagine that historically prostitution was kinda the equivalent of becoming a eunuch. Sure it maybe pays well, but you typically won't marry (I guess unless your stunningly beautiful?) and you won't carry on your family lineage (or the vague female equivalent)
