The only "don't" there is in this situation is: don't do it.  It will rub all the skin off of your penis and the pain - and bleeding, other drainage - could keep you from not only walking, but from wearing clothes for a week or more (and that's if you're lucky - if you're not lucky, the open areas will get infected and you'll have to go to a doctor and explain to him/her what you've done to yourself).  Even if you don't get infected and manage to get back into clothes before a week, do you have any idea what the scar tissue will do to your sensitivity levels?  Not to mention the fact that your penis may decide to stop working if that's how you're going to treat it ...

i have a relationship with a woman who is becoming increasingly dominant -- and experimental.  She wants to masturbate me using a tube of sandpaper.  Has anyone tried that?  Are there do's and don'ts?

As for safety, she says that, for my protection afterward, she will give my penis a nice wash with alcohol and iodine.

Lots of things are best left as fantasy

Go online and search BDSM abrasion play and you will know that any breaking of the skin can cause lasting injury.  If you have to try abrasion, have the usual precautions eg trust, safeword, first aid.

As for extreme CBT with tobasco sauce - thats actually safe and enjoyable for some men.

However, you have to mix the chilli with rubbing alcohol, use an eye dropper (not a needle for goodness sake!) and squirt gently into the urethra, use lube to get the eye dropper into the head (just a little way, not all the way like a sound) and make sure there is enough urine in the bladder to flush the sauce and alcohol out soon afterwards.

Be careful not to accidentally scratch the inside of the urethra and for goodness sake don't break the glass eye dropper. 

The tissue does swell and it burns like hell, but it does no lasting harm if done right.  Some subs like feeling bruises when they sit down; other like feeling like they are pissing fire for days after you play with them. 

Horses for courses, but tobasco is not quickly reversible, so let the sub practice with straight alcohol before mixing in anything hot.

Sounds like a case of new-Dommeitis.  She best try it on herself first.  This is right up there with the idiot I knew that thought injecting tobasco sauce down her sub's urethra was kewl.  She needs a reality check.  But its your dick... and the only one you have.
