firstly i have to give you a big thumbs up for not comprising youreslf for a quick thrill
to answer your question , i dont really know as i am a guy not a girl, but from logic i would say that girls would pick up on your virginity maybe because of your "eagirness" or neediness, it makes sense to me anyway, as when you have not experienced sex before, it might be hyped up in your brain....or maybe you suffer from "pussylitis" (from the movie 40 year old virgin), its when you put girls up on a pedestal, i dont know if you actually do that, but just in case you do...stop it, women at best are equal to you and most times are not worth the ****ing trouble, dont think about it too much - it will only make your "virginity" more apparent - to be honest from a male's point of view you have nothing to be ashamed of, as CAM said you should be awarded
