Looks like this thread is pretty dead, but DTR stands for Dual Tension Restorer, and refers to a device you wear on the end of your tool to stretch the foreskin, as if to "restore" it and reverse a circumcision.

I can't put external links, but do a search for DTR foreskin and you'll get plenty of info and pics.

Happy reading!
