A lack of breathing/moving space normally. Back to that spooning idea kind of; I can't breathe someone elses air, it's all warm and smells of something or another. Guess I'll never share a bed with someone T_T
Itchy things, like even if it's when you're in a clothes shop and bored, you get that (or..I get that) horrible heat sensation. . .bah.
Other than that I think that's all that makes me physically uncomfy.
