Best way to tell a guy you've fooled around with that you are a virgin?

You worry too much. He wont care that your a virgin or that you all went to second base. Have sex after your married... keep on the path. Why buy the cow when you get the milk for free. Or like Dr. Laura says how does it feel to be an unpaid whore. If he leaves you because you wont have sex with him then you know he is a dog, if he stays then you know he cares. Good Luck
