I remember three particular instances where my latex exam gloves fetish came from. They happened, I think, in 1990-91 approximately:
I went with my mother to visit my great-uncle in the hospital. A blonde nurse (not very pretty, rather plain-looking) entered the room, donned a pair of white latex exam gloves, and changed a bandage (or something, I can't remember). I watched her work the whole time. She yanked off her gloves and threw them away, which I at the time thought was strange. I didn't know about disposable gloves. I also remember her giving me a strange look before leaving the room.
The other instances was in December of that year. I was in fourth grade and our teacher (a young and rather prudish woman) had us make these reindeer tree ornaments. Put of making them involved staining popsicle sticks in brown varnish, which meant all us kids (and the teacher too) wore white latex exam gloves. I recall how nice and soft they were.
After everyone stained their sticks, she went over to the trash can and doffed her gloves and threw them away, which bothered me.
But what really got me into latex gloves was when I went with my family to visit my grandmother in the hospital. My older brother grabbed a glove, blew it up, and pinned it on a corkboard. I took a pair and put them on and it was heaven!
Consequently, I developed a bad skin rash from them. But I loved the latex gloves so much, I found a way around that. Everytime I take off the gloves, I wash my hands with soap and water. And I haven't had a breakout since.
As much I loved wearing the gloves, I loved having girls put them on. Of course, that's a rather tricky thing to do. I got into a lot of trouble in college because of that.
But it was worth it!
