As Lauren said any WG with some sense realises that she has an increased risk to exposure to STIs, that is why responsible ones will research all aspects and made the informed choices Traffors mentions.
Regular check ups, protected sex including anal and for a number of us oral (which is considered low risk) is a must and I believe I speak for all of us that we will refuse to see someone who requests bareback, even if he says it's ok and he'll wear a condom.
As said before the woman who goes on a night out, gets drunk and wakes up in a strange place is at much higher risk than we are.
Also to point 1, herpes can be transferred through simple skin contact and you could actually get it by touching someones coldsore on their lip (maybe accidetally by wiping your childs nose) and then touching your genitals when going to the toilet.
point 2 Yes you can get gonorrhea, syphillis and chlamydia from unprotected oral in your throat, but the disease needs a point of entry, if your mouth, gums and throat are in good health there should be a very low risk.
point 3 any form of unprotected sex can transmit HIV, not just oral and using protection is the answer.
There are a number of maybe desperate women/girls out there who will take risks due to addiction, force, debt or just want a quick buck and are pretty stupid in my opinon, but that is their choice and you won't find them on here. We are all intelligent, selfreliant, clued up women, who made an informed decision to use the godgiven assets, skills and talents we have to run our own business. It just happens our bodies are our commodity and together with our intellect are a very marketable product. To have a successful business we have developed computing, marketing, researching, accounting (we pay taxes like everyone else), social, acting, entertaining and sexual skills and look after our mental and physical health probably more than most.
This may be a bit strong, but forgive us if we get a little fed up with this stereo typing and the assumption that we don't understand the risks.
In your defence I have to say that at least you seem to be making an effort to find out more about us.
Can I please ask what made you want to know more and how you found us?
