There were previous reviews for Mary, previously of the 52 Greek Street Walk-down. She did not fare well in reviews, but unfortunately it's not practical to access that info on the fly.
In regards to not using your condom, to be fair, it would be very rare for a WG to use a condom provided by a punter. The fear is that some punter might tamper with condoms so as to break causing BB sex.
Mia had some good mentions, so I think she'll be a better choice for your next outing.
