For me, it started in my late teens / early twenties. I had a girlfriend who let me take provocative pictures of her and seeing her in the beautiful lingerie was a very big turn on for me. So I will have to say it started as a sexual adventure by trying on her lingerie. Since then I have never really wanted to ( or was to afraid to) 'come out of the closet'. I'm currently married and haven't shared with my wife but I often wear her panties while she's away or when I have time alone. So I suppose it still is a sexual thing for me. Ithink !! LOL
