My 4-year old daughter caught me and my husband having sexual intercourse in our bedroom. Right in the middle of a cumshot! She actually saw us when my husband's penis was in my vagina because she told me the 4 year old way: His stick was in whatever you call that thing!!!! But I have always thought the proper age to have the sex-talk with girls is from ages 9-11, since that is the age they usually start to make the change. But she caught us and I don't know what to say...
