Does “just the tip” count?

How does one truly “define” losing their virginity? Is it when they’ve had oral sex? Is it when they have intercourse? Is it when they’re fingered? Is it all the above? Can someone still be partially a virgin? Like me for example: I’ve had oral sex, I’ve been fingered, and I’ve had “just the tip” of the penis for vaginal...but is that really “sex???”

I know in my mind if there’s penetration then that’s “sex” but is that truly defining losing your virginity? How does an order female who has embraced intercourse “virginity” prepare themselves for “true sex?”
