CUrious especially about the people who aren't aroused by going to a real life doc but are by metfet. Are you in your own fantasy, do they involve specific other people, or fictional people you invent?
99 times out of 100, I am in the fantasy. Usually it involves one of two people that I knew in real life. One was a 20ish female, thin, cystic fibrosis patient with long brown hair. Mostly white with some Native American in her. I have always had a medical mask fetish of some sort, but it was meeting her in 2006 that made me OK with exploring it even more. She wore a mask in her daily life because CF, and the lung transplant that is usually sought for it, impairs the immune system severely. And so she wears her mask in my fantasies of her, except during fellatio, which always comes up.
The other was a short-haired, blonde girl in a wheelchair that I had seen at a summer day camp for those with disabilities in my teens. Dirty blonde, bronzed, kind of flat chested, wearing a colorful one-piece swimsuit and purple, footed tights. Sometimes I imagine her in a mask, too.
But as I get older and my mobility wanes, I occasionally imagine those two in bed with eachother, masks on unless they are using their mouths (kissing, giving cunnilingus).
