WHY DO adults still tell adolescents lies about sex ("Teen sex...", Real Life, 26 July)? There are several good reasons for everyone to be careful with sex - pregnancy, disease, exploitation, jealousy - but half the reasons given by David Bull to be celibate are quite false. It just isn't true that sex is over-rated, that it gets boring, that it is difficult to learn, that it doesn't improve with practice, that you have to do it in uncomfortable places, that you have to look good to do it, or that you have to fake it. As with smoking, drink or drugs, telling lies about sex makes things worse, not better.
