BlueBelle I agree with all you say until the last para. Consenting sex between two underage children of that age group will not be prosecuted, and if the parents coerce either of them into complaining out of fear of consequences of saying otherwise, or one has regrets the next day, it is very unlikely to go prosecution. Depending upon such circumstances, it would go before a youth offending diversion panel and maybe some educative intervention would be offered, if assessed as being needed, but definitely not sex offender registration - that only comes of clear intention to assault or rape by one of the couple, and would have to be proven beyond reasonable doubt.
