Why would your parents be having sex in the living room if they know you was out in the yard,and might of walked in on them?
and more to the point how could you watch your own parents anyway??
I was 17 also and am at 6. Hopefully this 6th will be the last... we're going strong! I'm approaching 30 now and most of my friends had been with 6 by the time they were 18.
