Virginity is a concept, not necessarily a state of being. Most people consider a virgin to be someone that has never had PIV (penis in vagina) sex.
There is the on-going belief that if your hymen is intact as a woman, you are a virgin. That’s one of those remains of the not-so-long-ago times when women were property and men bought them off their fathers.
Can the hymen break if two fingers are inserted? Definitely. Can it break with less? Yes again.
It’s up to you to decide what virginity means for you. I’m having a wild guess at the fact that your question comes from a feeling that not being a virgin is somehow shameful, sinful, frowned-upon or downright disgusting. Things probably told to you by somebody you consider an authority in your life.
I assure you – there is nothing inherently outstanding or shameful in not being a virgin. Just as there is nothing inherently outstanding or shameful about being a virgin. You are what you are.
Enjoy the ride. Explore. Stay safe.
