Answered by Shaykh Shuaib Ally
1) Is it true thet my wudu is broken if Itouche my wife? Is her Wudu broken too?
2) Is there specific guidelines in kissing one’s wife?
In the Shafi’i school, touching your spouse, and vice-versa, breaks one’s ablution. However, this most certainly does not mean that it is impermissible to touch one’s spouse for fear of breaking one’s wudu.
A person can kiss his wife’s lips, cheeks or other body parts, and vice-versa. Enjoying each other’s bodies is licit.
