I think we should all wise up, I am sure that the lure of money or ignorance, means that many WG's do do bareback. On another thread where I got insulted and lambusted because I mentioned I often ask girls if they do bareback, another poster confirmed he too asked. There is is no gurantee you will get a truthful answer, but we can at least tell from the response wether it seems likely.
