Starting Fresh

I recently got divorced after a long and unfulfilling marriage. One day, I stumbled upon an anonymous forum for DDLG/kink enthusiasts and decided to give it a try. It's been about two weeks since I joined, and already my world feels more vibrant and exciting. Last night was particularly eye-opening: I played the role of a submissive in a session with someone who called me their little, and let myself get lost in the fantasy. There were moments when I felt so vulnerable and exposed, but also incredibly safe and cherished. It's like I've been sleeping for years and finally woke up to this new side of myself. Is it normal to feel both terrified and exhilarated by such intense emotional experiences? What tips do you have for someone just starting out in exploring these dynamics?
