I'd say look through the forums for ideas, there's a lot of them.
Then I'd suggest listing what kind of self torture... CBT, nipple, anal, all over?
don't forget to list things you like, dislike and limits you might have.
Then enjoy
If u have somewhere to tie some ropes from then tie two ropes from two beams so that the middle of both ropes meet about waist height. Now slip one loop from yr ass side and one loop from yr front. Now loop one over the other loop then put yr cock and balls through the joined loop and the let yr body weigh squeeze yr cock and balls. Now tug till u blow. Do over and over till u can't do anymore
