My experience

Not exactly anecdotal I guess, but I've never felt any attraction to my siblings. <br><br>We're a family of 4, oldest, middle, youngest, and youngest youngest. Our mom's always talked about how it's absolutely off-limits, and it's probably 50% what's kept us from ever doing anything, the other 50% is just lack of interest.<br><br>Growing up, we never BBQ'd anything. Instead we had a lot of steaks and vegetables. We always wondered what it would be like to BBQ food and it was a point of contention for a little bit, but we never realized that it was in the end 100% worth it because of the result. <br><br>BBQ food always tastes better than any steak you could get.
