- If a man and his wife are unclothed under a blanket close enough that their skin touches each other from the waist down, he should not recite Krias Shema Sh’al HaMitta nor Hamapil without a cloth seperating between them. (ShA 2 – MB 4,6)
- This prohibition does not apply to thoughts of Kedusha. Therefore, it is permitted to think holy thoughts during intercourse. (BeH “mimasnayhem”)
