Latex is and always will be my first and foremost. I love If there was a piece of media that really made me like it I couldn't tell you, I've been fascinated by skintight clothing for as long as I can remember.
I just love everything about how it frames the body. The smooth, almost soft texture. The subtle sound of it moving with or against you. Shiny or dull it has a way of accentuating the form and making it so much more than it is. Temperature, the way cold air chills it against your skin and a hot shower warms it. Even the smell gets my attention, I've noticed different scents between some sheets that can be striking.
But it's fucking expensive. I went so far as to learn how to make clothing out of sheet latex (still like $12 per square yard on the low end) and have amassed a whole wardrobe of homemade leggings, shirts, skirts, gloves, stockings, jackets, and various restraints all fashioned out of rubber (with some special things that were bought). Wearing it isn't even just a sexual thing, I've worked pieces into normal-passing outfits and worn them out, a shirt showing under an open jacket or button down is usually safe enough. I haven't been able to wear it that much lately due to personal reasons, but those few minutes I've been able to find have ben wonderful, even though they're typically spent relaxing or doing chores.
If I wanted to analyze it deeper, I'd have to say a big draw is how it not only improves the body but protects it. Or maybe protects me from other bodies, could be that I have issues with people or sex feeling gross what with all those fluids moving around. Hell I even enjoy how condoms feel, and the different colored ones are just fun too, much more aesthetically pleasing than natural. Maybe I feel guilty about feeling sexual things towards others and cope by focusing my desire inwards, but poking at that sounds like a way to dig up a whole bunch of personal problems that I don't want to deal with on the porn board.
