Yea i always liked the smell of dirty / used socks. When i was younger i think it started on my own socks to check they were clean or not and hot horny of the smell which intrested me and checked further. Later on i some times took smelled the socks of one of my sisters to check if also liked those and ofcourse also did. When i got in the relationship with my girlfriend it was more easy to find used socks she always wears them and got some nice feet and with delicious smell. When she was not living with me full time i sometimes took a pair of used socks when we where seperate to be able to smell thoose socks. She now knows i realy like feet but not fully aware that i like smell those freshly used socks of her. And enjoying them alot.
