Because I'll admit I'm not an expert, but I'm willing to learn. I think the first picture is a guy with a weird shaped (but creative circumcision job!) schlong engaging in coitus with a rather rotund lady in a bathroom. Notice the toilet on far left, viewed from above. That's not very scientific to me! The next pic is a moose drinking with a straw (I've seen a lot of moose and this is a first except for Bullwinkle) and it has an arrow in it's antlers! That's not educational, it's bad archery versus a gifted moose.
luckily my wife and I had both our kids the old fashioned way. We concieved almost immediately after getting off birth control, which is fine because I'm pretty lazy. If I were any lazier I'd just marry a prenant women.
