I was in Kentucky visiting family and my cousin's friend's sister is young about 12 or so years old and was not sexually educated when a guy only 3 years older then her started touching her private areas the young girl asked him what he was trying to do and he said he would explain afterwards and he proceeded in sexual intercourse with her telling him she didn't understand. Afterwards he did not explain truly and she came to us later asking what sex was and told us what the guy did. We need to know was she raped?
If she was under 16, it's rape. A child under that age cannot consent to intercourse.
If she's older, it may still be sex abuse, which includes subjecting a person to sexual contact without express or implied consent. It may also still be rape, but I'm less clear on how Kentucky courts define implied consent.
