Oral Sex and Dental Dams

Yes and no.
If I were to go down on a girl, I'd for sure use one.
I have them incase a guy would like to use one on me, but that has yet to happen.

I think having them, and making the guy aware of them is important, but in the end it is a personal choice.

my ex used one on me !

Nope i havnt used it either

havent used or had anybody use one on me.

i don´t think thongs will work for that in my opinion

I have never used one.

Some people use them, but honestly I'd rather not receive oral at all.

I've never used them. Of course, if you want to be quite cautious, then they're a great option.
