Lil Wayne - Sucker For Pain Lyrics Meaning

There are two voices in the song: the dominant and the sub. They may be suckers for pain because :
1. being so infatuated/in love with someone that you become a 'slave to their games' even though you know they are a toxic 'flame' you want to burn just to feel the pain of being hurt by them. The pain even 'soothes' you.

2. Inflicting pain empowers you and is a way to manipulate others. You 'tie them up' to show them they are helpless and you are in charge. This could be constant teasing, negging, gaslighting etc.

3. A BDSM relationship of mutual consent based around a shared kink.
