text: You didn't give enough information.\n\nDid you have sex with a 16 year old boy? Girl? what country? what state?  Different states have different laws on age of consent. In some places, it's as young as 14.  In some, it's as high as 18.  Here in Texas, it's 17, but two people within three years apart can have sex (meaning 16 and 16 is ok legally).\n\nYou didn't say if your question was a legal one or a moral one.  I'm inclined to believe it's OK morally,and likely to be OK legally, but again, depends on where you live.
