Any form of sexual enjoyment between the husband and the wife is permitted with the exception of what is explicitly prohibited by the sacred texts.
The prohibited acts are: sex during menstruation, sex during post-natal bleeding, and anal sex.
Allah says: “Your wives are a tilth for you, so go to your tilth when or how you will.”
As for during menstruation, the Prophet (peace be upon him) said: “Do everything except intercourse.” This means that the husband and wife can do everything with one another excerpt for actual sexual penetration.
And Allah knows best.
