What kind of influence do you think this is having on teens?

People vary - even teenagers, some will want to wait and others won't. I think that the parents who are supervising are naive - the teenagers will just meet after school and have sex in a field or wherever you won't stop them if they are determined. I think the condoms on offer is a better idea - although the girl should be reminded that what happens is up to her and she has the right to change her mind at any time. A girl has the right to walk round her bedroom in her pants (underwear), getting changed in front of her boyfriend and this doesn't mean she wants sex. That's the important part of sex ed.
