Did you bleed during your first time? and how long did the pain last?

I’m having my first time soon, and I’ve already got a liner, towel, change of panties in my bag. Every story IRL I hear seems like one out of a Stephen King movie... can’t tell if they’re pressuring waiting till marriage onto me (wouldn’t doubt it) but I’m scared... If anyone can help me out (got condoms & birth control btw) or maybe share their story I’d be thankful. He’s average size also.
