You are not a creep if you find yourself sexy with your disability aids. full stop. If your partner is disabled, you are not fetishizing them if you find them sexy when they're in their wheelchair, or wearing their diaper, or have braces on, etc.
Disabled people are allowed to feel sexy and people are allowed to find them sexy. People with facial/limb differences and other physical differences are allowed to feel sexy and people are allowed to be attracted to them.
The problem comes from lack of consent and dehumanization. Expecting all disabled people to fit your sexual fantasy and sexualizing them openly without their consent (i.e. posting/reblogging normal pictures of a disabled person on your fetish blog or sexually harassing a disabled stranger) is fetishization and horrible. Asking us how we have sex or taking secret photos of us to jack off to later is creepy and crossing the boundry into dehumanizing fetishization. Seeing us and our sexuality as an oddity or a funny joke is not okay.
Reminder, sex toys were first and foremost created by and for disabled people. We have always been having sex and have always been seen as attractive by our admirers, without them fetishizing us. Having sex with a consenting disabled person isnt rape, and yes it is possible for us to eagerly consent! While some disabilities make it hard to consent, that isn't true for all of us.
We get horny, we have sex, we jack off, we wear sexy clothes and show off our bodies. We aren't freak shows for abled peoples amusement nor objects for fetishization. We aren't poor innocent virgins who don't know what sex is, we are a diverse and beautiful community all connected by our disabilities.
