That is interesting. Putting aside that I am not particularly interested in having some per se stricture inculcated in teenagers against sexual activity (in fact I would oppose that actually come to think of it; one size does not fit all), it would seem to me that if one wanted to combat sexual activity, the only way to do that would be by abstinence. Is there a way that one can be both abstinent while engaging in sexual activity?
I don't think that the goal is to fight sexual activity, but rather unwanted pregnancies, which is the cause of abortion.
