My cat won't leave me alone!

Kristen
My cat Roxy is always wanting to be on me, especially curled up like this on my shoulder/chest. I like that she's so lovey, but she is mashing the hell out of my boobs! 
She stepped on my nipple earlier and I almost cried. I can't even eat without her trying to be all up in my face!
Anybody else's pets going nuts?!
