A guy slightly put the tip of his penis inside of me. i was a virgin before. did i lose my virginity? i want to know if the hymen is still intact or not?

Some people believe that you’re not a virgin if your hymen is stretched open. But having a hymen and being a virgin are not the same thing. Some people are born with hymens that are naturally open. And many other activities besides sex can stretch your hymen. ref: https://www.plannedparenthood.org/learn/teens/sex/virginity

The definition of virginity sometimes varies. For most, it is never having engaged in partner sexual acts. The presence of an intact hymen is not a valid definition. Some women are born without or lose it to non sexual activity. Some forms of sexual contact do not involve the vagina, but transfer STD germs. In my world you are not a virgin if a penis went in, no matter how far.
