12 is a pretty common benchmark, though can often be younger in the races that are faster to develop secondary sexual characteristics. It's retarded that the cucked law expects us to psychically know a girls age and be able to remember it even when she looks like a legal adult.
The majority of girls I've assumed to be breeding age and legal have been preteens and I want to avoid prison so I don't even bother trying to interact with with women that aren't specifically pointed out to my by my mom as being of legal age. Shit, I've seen 14 year olds that I've guessed to be in their 30s.
