@hnhall32 Your son knows no such thing. How do you think women get the HPV? Although, the younger generation is getting vaccinated for some of the cancer causing strains of HPV. Many men are assymptomatic for trich and chlamydia, they have no idea they have it, and are giving it to other people.
When people are very abstinence oriented, I worry they have no clue what their kids are doing, but of course that does not apply to everyone, maybe you really do know the truth about your sons sexual life.
Even if people are abstinent till marriage, if their parter has had sex, all that is out the window, unless they have been lucky, or used condoms religiously. Except, as I said, there is a vaccine for some HPV now.
In my opinion condoms are closer to 100% than abstinence, because most people have sex. I rather they be prepared, know the facts.
