I know many people avoid the DIY providers. Personally, I know a few that give a phenomenal TM and look good at the same time. Sometimes I just need an exceptionally good massage for my old body, and the added teasing with the DIY option makes the TM that much better...in my opinion. For that reason, I have no issue salami bopping myself. However, I never know what tip. I'm usually very generous, but was curious what others tip in this scenario.
