Precautions are vital of course. So, using condoms is a must as most of us agree.
However, in reality all WG's have at some point barebacked or are still now barebacking someone, be it pimp, boyfriend, regular punter, or some fit guy she met in the pub / club.
Many WG's have BB photos, and most will say they are with their boyfriend (pimp or whatever).
At the end of the day if you fancy her, just go for it and use a condom, none of us expect exclusivity in her bed!
