Honestly, I used to use Links Organizer many years ago and it is an outdated software and I would not recommend it to anyone as it might be broken by now or it will be very soon if the developer does not release a major update for it.
If you want to control the inbound links coming from your adult site then if you are using the WordPress as a platform, then Shortlinks by Pretty Links is your best bet and it is free.
If you want to keep the track of the outgoing backlinks then create a simple spreadsheet in Excel, Word, and Google Sheets or in other programs or you can even use the simplest text editor to manage them.
