I do not think that what is normal for any age is defined. In general the trend is away from even using the term 'normal' in most contexts - "typical", maybe, but not "normal". One reason for it is that "typical" is a statistical reference (an "is"), while "normal" is, well, a normative statement (a "should"). But from what you can glean from this forum if you spend several days reading its archives, you are somewhere in the middle of the range of what can happen to preteens and teens.

More to the point: what is happening in your sex life now? What is the reason for your self-discovery and sort of autobiographic inquiry?
