Since I brought up the kink test, I thought I'd dig around for some other online sexual experience tests. The 'purity tests' have been around for a long time (early 90's when I first saw them) and so they've been thought about a lot.
The purity test is probably a better test of the real sexual experience of people than the kink test I posted earlier.
