I think there are plenty of male oriented ideas out there, but here's one. Use a soft rope to fasten a double crossed loop (clove hitch) round your ball sack with the ends dangling down behind. Then sit on your heels and tie one of the ends to each big toe. This can be turned into a very male oriented hogtie, but you'd better do it on a thick, soft mattress or pad or a certain very hard part of your anatomy will have nowhere to go.

A great place to look for self bondage ideas is Gromet's Plaza (www.grometsplaza.com). You will find lots of fictional stories there, and practical ideas for self bondage, male and female.
