Well davelj, assuming you are interested in a sexual relationship, the first risk is picking up something extra from the deal. The second risk is pregnancy, though maybe you’ve had a snippy snip. The third is emotional so you might discount that completely, but I’ve never found opening up to people to be risk free.

As to the odds being against it, every woman I’ve encountered says at least on the surface, they aren’t interested in anything short term. Maybe its BS, I’m certainly no expert. I tend to take people at face value, at first.
