First time sex problems?

[Pinapple]

So me and my bf had sex for the first time, on the third time trying. xD. Out of curiosity, I wondered if most people have problems?
We had to try a few positions and places, and I kept having to stop him because it got too painful.

I didnt really run into any problems with my gf but I didn't really last that long lool
