Ezoic
Ezoic allows you to choose which categories of ads are shown on your site, in the same way that AdSense or the Google AdExchange does.
If you download the Ad Categories app you can block any 'sensitive' ad categories which you do not wish to show on your site.
You can do this in the Monetization area of your Dashboard and scroll to Ad Categories.
'Gambling & Betting (18+)', 'References to Sex & Sexuality' and 'Sexual & Reproductive Health' are automatically blocked - however, you can choose to enable these if you wish.
