I do think that guys don't mind me not wearing anything, but most of the time what they want is the "no-makeup" look that you girls mention. Either that or just a perfect girl to start with
Most of the time, if I wear a light foundation, concealer, bit of blush, light eyeshadow and mascara, and I specifically ask a guy if I'm wearing makeup, he goes "hmm i don't think so...but you're pretty without it". I also used to have a boyfriend that i never wore makeup around, so once I wore mascara and blush, and he spent all night telling me how beautiful i was. I honestly think most guys don't realise we're wearing makeup unless its a smoky eye or red lips.
