Loose collection of sex education material reffering to socalled "interracial" sex

Of course, in the title it should mean: "Referring"

Sex education not only related to "interracial", but also "intercultural" needs

Here we can collect a lot of government official sex education material, as well as that of NGO's and volunteers (us, this forum). Before we can start a more elaborated thread that is like a course, we can add picutures and descriptions what shouldn't be missing describing the anatomy of (socalled "interracial") sex. The education would be incomplete without comparison, right? Considering that if it happens in school and / or university it schould be actually a holistic education. There are many more biological, physiological and anatomical aspects to add. For example: How about the examples of recessive and dominant genes that can be illustrated as well (in biology class)? All that said, maybe you like to discuss it here or with me in private, I have the idea to start an own thread for all of this. We first can collect detailed data, then see what others know to add. It might be also possible to translate in European languages when the material is finished later, so that the European market also can have use of the education aid. Message me, if you like : )

First page of (government sponsered) sex education site could be: Tolerance is important, for example when it comes to different hygiene habits and stronger/ more masculine scent of body, penis, testicles and sweat due to different physiology and for example higher testosterone levels.
 
When adding the education about the semen production and male genetalia, like here...

.. it shouldn't be forgotten that there can be differences in the quality an quantity of sperm and how it is meassured, called when there is above European average. Don't forget that the education can not only function for young European people, but also as help for (African) immigrants.

right: hyper-spermia (African sperm as compared to European average, named "normal" here)

things to examinate (and to come to conclusions when comparing): left: volumen (overall amount); mid: how sticky it is; right: optimal pH of healthy sperm: 7,2 to 7,8. 7,8 is considered aggressive (usual in African ejaculate) and will "more than" just survive sour milieu and acid medium of European vaginal slime inside the vagina. It is most probable to rest there longer hours then.

with the eosin colouring the sperm cells are made visible in the ejaculate, so they can be analysed under microscope: are there dead or living ones, how many are there in one drop? The concentration is found as well as if they look healthy and have no disformations (morphology) and you can see how lively they move (motility).
