Hi, welcome to the forum 
Theres quite a few of us on here with all sorts of different challenges. Plenty of us have had a go at bondage so hopefully you should be able to find some suggestions on here.
Theres a thread where we’ve been swapping tips and experiances here that may also be a good place to have a dig. (this one is nice too)
Ive got M.e./c.f.s and have been trying some bondage and sensory play solo, which I’ve really enjoyed.
Im not the most experienced though, but this is a good place to come for advice, everyone is very friendly and helpful here.
