As someone who's been in some strange niches over the years, I always hate it that so many keyword tools don't give you any results for more adult related niches.
So if you're interested in finding adult keywords then leave a message below.
Niche Laboratory did originally have an adult mode. However I had to take it out as the original data source closed down. It probably still is quite good for finding adult keywords. However I haven't put in any specifically adult orientated data sources.
As for adult niches - are they any good?
One word - YES!
