Ok, here is how it goes. Im no guhyancologist, but I am a sex maniac and pervert... Dont hate, its the guys like me who get the job for more than 4 hrs. Ne way, basically, we cant really tell if ur a virgin by lookin at ur vagina, but, I can tell if you have had lots of sex, or at least repetitive sex in a short period of time. If you have sex alot for a longer period of time, and many times, ur vagina lips tend to hang down. If your a virgin, ur vagina will not have these "lips" as I call them. There is a way to tell if uve given oral sex before, but it not aways accurate. If your good at it, then we can guess uve done it, but if u wanna seem like a virgin (oral sex wise) try it bad, and progressivly get better. So the first time, accidently bite his slong, etc, and then just get better at it slowly. Well, I hope u all have fun. P.S, ne 1 wanna cyber, pm me, lol.
