Well me and my girlfriend had sex for the first time today and we didn't have a condom so we did it anyways..now she's parnoid that I came inside of her which I know for a fact that I didn't..even if I did wouldn't she be able to feel it inside of her?..I pulled out before I came so I know I didn't do it inside of her..but now she's got me scared to death..what should I do?
