does sex actually hurt the first time?

Sorry in advance if anything is funky about this post, I don't normally use reddit and didn't even realize I had an account until a couple days ago.

I'm a 15 year old girl so this topic has been on my mind a lot recently. I promise I've done my research but all I've seen is either 'it shouldn't hurt' or 'you'll probably bleed' and I just really want real answers from real people. I feel like I am not far away from this first time experience and just want to know what to expect.

edit : i read through all the comments, thank you all for the kind words and great advice! there were a lot of helpful and encouraging comments that have helped me feel more at ease.
