Masaail relating to intimacy

Facing the qiblah while being intimate with one's wife

Q:

1. When I am intimate with my wife, we sometimes face the qiblah while kissing, hugging, rolling on bed, etc. But we are nude and we face the qiblah. Though we try to avoid it sometimes. Is is a sin to face the qiblah when nude, whether from the front side or back.

2. Although we know that we should put a sheet over ourselves while being intimate but sometimes knowingly we do it without a sheet and towards the qiblah. Are we sinning? We know that while relieving oneself one should not face the qiblah and we don’t do it while relieving.
