It started with pantyhose. My ex hated it & would get very upset whenever she discovered I was wearing a pair.
She always warned me that wearing them would progress to wanting to look completely like a woman.
Many years later it turns out that she was right & I am now developing a full wardrobe.
As mentioned in my introduction she's ok with it now. Although she still sometimes teases me about how my pantyhose turned into my slippery slope.
