Well guess what, she was old enough to travel on her own, then she was old enough to have sex while being on her own, don't get me wrong, if he raped her then he should fry, but if it was of her own free will, then that is good enough for me, weather it was my daughter or not, just because it was your daughter does not mean it was wrong, kids will have sex no matter what these days, I had my first encounter at 14 so what, my father just told me to make sure that I was using protection, other than that, the girl I was with was having sex with me at her own free will
and your age thing is a crock, you can join the military and die for your country as you should know at 18, but at that age you can't drink, but the goverment will let you die for them before you turn 21, go figure
And also by the way I have had many 3 somes and hope to have many more, I hope that does not mess you up to much, but many of us do that, if you never had the chance to do it, you don't know what you missed
