Is it permissible for a man to wear his wife's clothes, such as an abaya or loose shorts, during intercourse for foreplay and without the intention of imitation, due to sexual weakness and a need for arousal through soft clothing?

A man is prohibited from imitating women, and this prohibition includes wearing their specific clothing, as reported by Ibn Abbas and Abu Hurairah, may Allah be pleased with them, from the Prophet (ﷺ): "Allah's Messenger (ﷺ) cursed the men who imitate women and the women who imitate men," and "Allah's Messenger (ﷺ) cursed the man who wears women's clothes and the woman who wears men's clothes." Thus, a man wearing his wife's clothes is considered a perversion of the natural disposition (fitra) and a gateway to effeminacy. The intent to imitate is not a condition for its prohibition. The questioner is advised to seek treatment from specialists, along with frequent supplication.
