All my kids (2 girls and a boy) have slept in my bed on and off when they were younger- if they were sick, had nightmares, etc. My youngest who is 10 still does occasionally. My 12 1/2 year old no longer does and I wouldn't encourage it. My son stopped at about 10. Ill admit that it did start to feel a bit awkward with my son where it didn't with my girls. That's not a judgement, just how I felt. However, I wouldn't encourage a teen of either gender to sleep in my bed, just because at a certain point I think kids need to be able to comfort themselves. Again, not a judgement but something to think about.
