Wilson bros, I would call this a truely comprehensive AR and keep up the good work. Let us know if she decides to come back and cleared medically.
In terms of probability and risk, both WL or ML or punters are by nature high risk takers and so not a good mix. If I visit a WL or ML regularly, I would sometimes get offered free BBFS and sometimes simply have the doms off skillfully, which can be hard to resist. You have a split moment to make a decision and worse still if you have a 20 year Chinese WL begging for it in an overnight booking. The standard line from WL before or afterwards would be I get regular STD checks or I won't go after you if I get pregnant. My response would be to assume I am not the only one offered this on probability and move on.
