Decades ago, when my girlfriend turned seventeen, I was going to be sixteen for a couple of days still. Here in Germany, that's the line between consensual sex, except for some special rules that involve parental agreement or marriage. I made a funny comment about it that she would be abusing me for that time if we would physically engage. Well, it was just a kinky fantasy, and I wished so she would. Because we were engaged consensually.
Laws are strange, sometimes. They draw fixed lines...
