Statistically, porn surfers are commonly aged between 26-53 according to a research document i found several years ago however this has more than likely changed since then.

I know when it comes to certain niches in the adult industry they are more likely to sell to a specific demographic. One good example of this is the tranny niche, the target audience for this niche is between the ages of 30-55, usually affluent business types such as wall street types etc.

Of course this doesnt always hold true but if you can target your surfers demographics when it comes to marketing specific niches it can drastically improve joins.
