Am I considered a virgin? Can a kohen marry me?

I’m a 29-year-old woman and have been a virgin my entire life. A few years ago, I had an experience with a guy where he attempted to have sex with me. Although only part of his tip entered me, I immediately pushed him away in shame, realizing what was happening as I never consented to piv and stopped everything from progressing further. I feel really bad about this incident and haven’t had any similar experiences since. I’m curious to know if a kohen is forbidden from marrying me due to this situation. Since it wasn’t full penetration, am I still considered a virgin?
