Introductions discussion

Greetings! I’m the submissive guy in my girlfriend’s/custodial partner’s relationship, and I hail from Germany, so please bear with my somewhat rusty English;-) Self-locking has been part of my life for quite a while now, but I never stumbled upon the perfect woman to keep hold of my keys. When I started dating my current GF some time back, I shared my fantasies right away. She was slightly taken aback because she’s pretty much vanilla and hadn’t heard much about this lifestyle before. Fortunately, she was willing to give it a shot and took over key duty for me. Initially, her goal was just to accommodate me, mostly letting me out whenever I requested it. Lately though, things have shifted (as detailed in another discussion) and I’m starting to venture into new territory with her help. Fingers crossed everything goes smoothly… Pleased to join this community; it’s always great to be surrounded by folks who get it:-)
