Shaving legs

Madison • ❤️
I've been shaving my legs for a while (I'm 18) but am never able to shave my legs in the winter because whatever touches my skin, will give me a rash: jeans, leggings, tights, etc. I even get a rash a few days after shaving just from brushing against something with my bare legs (no hair, obviously). 
I don't know if it's just "sensitive skin" though because makeup, and face washes are fine on my skin, same with body wash.
Does anyone else have this problem???
