I often into self-tie in the past when i can't find anyone to tie me up out there
the easiest position is hogtie... i knew i guy on youtube that he likes to tie himself up all the time
he used a coil of rope which wider enough to put both ur hands into it... than tie ur feet together... again tie a rope between ur legs... then make a loop knot at the end of that rope and put it on the coil u will use to put ur hands into it
After the prepare, all u have to do is lie down, put ur hands into the coil behind ur back... and with a pull from ur leg... the loop knot will tie tightly ur hands... and game on
WARNING: do not pull so hard or ur hands will be immobile... Maybe u should make the coil wider so u can escape easily or prepare a knife near ur place to cut it out
I think u should try to find someone trust enough to play with instead of play self-tie... cuz it's kind of dangerous... and sometimes i thought i can't out of my own tie
Have a nice day
