I'm 27 and i feel like i'm too shy to date? Ordinarily im an aggressive and bold girl?

but as soon as a guy gives a look of admiration or a compliment, I brush it off and look down and practically run away. It's embaring. yes, i've never had a boyfriend and i'm still a virgin. sometimes if a guy gives me a compliment ill brush it off and say he's just saying that because he's looking for . In hindsight i've done this to a few guys who were really nice guys but i didn't want to be put in a romantic situation because it makes me nervous and self concious.
