Hmm I say find some french and english health sites.

You have to take in concideration on the number of peeps in thoes countries that already have stds. Who ever already has more is more likely to spread more!

Women are usually the ones who get them more because of our genitals. Guys genitals are on the outside and the bacteria or viruses can be more easily wiped away. Girls genitals on the other hand; are a 5 star hotel for bacteria! Warm moist and the perfect place to call home!

At least this is just what I think I could be wrong! If I think of anything else i'll be sure to add it!
