>As a sociologist how do you explain this?
There's absolutely a cultural aspect to fetishes: people tend to fetishize illicit things 'naughty' things and what constitutes naughtiness has changed over time, think about Victorian era people and their ankle fetish.
But more intimate statistical data also heavily implies a genetic and gendered factor. Some fetishes may be fundamentally ingrained into people's minds and only at a later point, due to exposure/context, do these impulses develop a "face".
