Is it legal to sell condoms to minors?

definitely. and if anyone tells you otherwise, they're wrong.

answer 2 It will be a curious or perverse community in which it is illegal to sell condoms to minors.

I can imagine such a society, but my views need not be exposed by identifying such.

Other than in a small enclave in Italy, I cannot imagine them not being available.

In NZ they are an open display item in supermarket and pharmacy.
