Sleeping with a boy in the common sense of this expression is really bad.
Sleeping with a boy in the way you described isn't bad, positively said it is a great joy. I had this experience only once...

If you like to read:
I spent one night at friends' house (just knew them distantly), but they had no bed for me and asked their only son (whom I had not really known before) to give me his bed (he should sleep with his parents). I said, no problem, I'll sleep with him, for I also have some younger brothers, no problem... ;) They allowed (they do not know that I am a BL), and we enjoyed... we talked a lot, he had quite good practical questions on the Bible which we could discuss very privately, being so close. He was 11, so handsome, and did really cuddle up to me, no need for distance... Of course, we did nothing more, I just hold him in my arms until we slept. I felt he really loved it, I cannot say why he was so open to me, not knowing me before. But I can say, it was one of the best nights I ever had. Unfortunately, they live far away from me, did not see him since then...

btw, another example that boys do feel if we really love them in a good way - they will love back. I am saying nothing new, but that's the reason why so many pedos can do really good work with kids.
