Help for beginners with self-bondage basics

Alright, I’m here to follow through on my New Year’s promise. I really get turned on by the concept of self-bondage, but where does one begin? Give me a straightforward, basic scenario. Keep it affordable and unobtrusive. Please be gentle with me. I realize I might sound a bit inexperienced, as most examples I see seem quite intense for someone just starting out like me. So let’s stick to the fundamentals - how did those who know what they’re doing get their start? Maybe others lurking here would benefit from an answer too, making this thread useful.
