Looking at the above responses I'm interested to know who has sons and who has daughters because there seems to be a bit of excusing going on for the boys.
I'm not excusing anyone, and I have a daughter and a son. I am aware, however (maybe as my teenage years were less protected than yours), that young teenagers, both male and female, can get carried away, particularly when inexperienced about sex, and that alcohol muddies the waters enormously.
I think that assumptions such as yours are unhelpful too. Nobody, as far as I can see, is excusing rape or coercion in any way, but a drunken fumble can quickly lead to things going further than expected, and denying that, or assuming that anyone who recognises it is 'excusing boys' only makes matters worse. Girls have sexual impulses too, and not all boys are predators - both sexes have to learn the signals and etiquette involved, and from what I hear from younger friends many adults struggle to get it right.
I think that at least part of the answer is to educate young people about the effects of alcohol, but I appreciate that this is easier said than done. It is only when someone has experienced being on the wrong side of a few glasses of wine (or young person's drink of choice) that they can understand the impact that it can have. If you are lucky enough to have this happen in a protected environment, you are far better prepared than if it happens somewhere with other unsupervised young people who are equally the worse for wear.
