Is the wudu (ablution) invalidated when a man touches the skin of a woman or when a woman touches the skin of a man?

Dear Brother / Sister,

According to Hanafis, wudu is not invalidated when a man touches the skin of a woman or when a woman touches the skin of a man.

According to Malikis and Hanbals, wudu is invalidated if the man or woman feels a sexual pleasure when their skins touch each other. According to Shafiis, wudu of the person who touches and who is touched is invalidated if the skins of a man and woman touch each other even if they do not feel any sexual pleasure.  (see Wahba Zuhayli, islam Fikhi, Abdest bölümü)
