I wanted to ask if the compulsion of wearing a ring only in the last two fingers of first right and then left hand is only for men or for women as well. Please guide.

It includes both men and women. And it’s not a compulsion. It’s a recommendation. Here is a hadith in Makarem al-Akhlaaq:

في (مكارم الأخلاق) عن الصادق (عليه السلام) قال: قال رسول الله (صلى الله عليه وآله): أنهى أمتي عن التختم في السبابة والوسطى.

The Prophet (s) said: I prohibit my Ummah from wearing a ring in the middle and index fingers.

And the word Ummah includes men and women.
