I recently had an eye opening experience, that made me think it would be appropriate to list (in jest) things a provider shouldn't do during a session....and of course I'm sure the providers will have a few for us hobbiests. Here's a few of mine:
1. Don't leave several condoms floating in the toilet
2. Don't leave bloody towels in the bathroom
3. Don't pick crust out of your mommy parts and stick it in your mouth
4. Don't leave dozens of condom wrappers in the trash
5. Don't lose the donation, go ape-shit, and try to call LE
6. Don't bring a non-provider girlfriend to 'observe'
7. Don't walk me through a living room full of other people, to include screaming babies, to your room
8. Don't get me hard with bbbj and try to mount me bareback
9. Don't spit baby gravy in the trash can
10. Don't show up at the door with a russian body guard
All have happened to me...and made me think 'wtf am I doing?!?!'.
