Not using a Rubber, not using your big brain, that's for sure. There are other threads on here where the sp complain that they are approached for bbfs and how they feel disrespected when asked. I think bbfs happens a lot more than we guys realize. I always carry spares, although i respect that sp like to use their own. I know i take a chance with bbbj, but is so much smaller than bbfs or bb greek. I actually enjoy watching an sp be sexy when she slips on the cover, especially if they deep throat it.
I've been busy playing on POF the last few months, lucky to finds some fun swinging couples. It is/was so much fun, but I found that the POF world is STD unaware. I always brought my own condums, and ususally was the one to insist on using them. This is a very fun game we play, and its up to us to keep ourselves safe. Btw, if you're on pof, and a girl is looking for a "generous man", its an sp and she wants money for her "intimate encounter". I found a few on there.
