Lots of variety there! Thanks for all the replies - I feel happier knowing there's others out there!
I'm 23, look 20 and feel 30! I've finally stopped being ID'd so hopefully I'll avoid the looks.
I looked after a friend's kid in a shop while they bought his Christmas presents (I was about 18) and a guy walking past and called me a slut. Since then I've worried what people think! I'm going to stop from now on!
