When I Played Mommy and Daddy's Little Boyfriend

I've always been close with my partner, who's 18+, but we recently started exploring DDLG dynamics as a way to spice up our relationship. At first, it felt liberating and fun, getting dressed up in boyish clothes he picked out for me, being called 'sweetie' or 'honey', and even acting like I was in high school again. He enjoyed taking on the role of a strict but caring parent figure who would teach me and discipline me when needed. It started off as playful teasing, mostly verbal, with occasional spankings that left my skin warm and tingling for days afterward. But then he got into it too much and things took an unexpected turn. He wanted to push the boundaries further: more frequent 'discipline' sessions that escalated beyond just a swat on the behind, they included spanking paddles and even belt whippings at times. It's not as bad as it sounds, but hearing myself beg for mercy or crying out in pain while being punished has left me questioning everything. I'm worried now about how far we've gone and if there's a point where it becomes too much or crosses into something unhealthy. Deep down, I feel like maybe I want to stop, but part of me still craves that attention from him. I guess what I’m really wondering is: am I being unreasonable by feeling uncomfortable now? Should we just take a break and reassess how deep this DDLG dynamic should go, or is there a way to make it work without any lasting damage? What would you do if you were in my shoes?
