No he can not. The vaginal opening can expand without the hymen breaking.
no the only person who can tell you is herself
A doctor can tell by doing a pelvic exam.
You can go to a doctor and get a scan done, he/she can tell you whether it's a boy or a girl.
the only way to to tell if a girl is a virgin is to simply ask her if she is a virgin
if the girl is freaky tell her u not a virgin but if she not a freak tell her you are a virgin
Since the hymen can break quite easily many women don't have it when it's their first time and the doctor can never tell why it is gone. So the doctor can not tell.
there is only one way. if she is her hymen will break when she has sex and it will hurt!!
That depends on who the girl is - if she is your girlfriend, or someone you want to be close to, then tell her the truth. If not, it's none of anyone's business whether you are or not.
Not unless ur a doctor, the average person won't know. Or if u had sex with enought virgin to know by experience.
