Is sex really like that (10-15 minutes of pumping until you cum and can stop)?

I 24m have never had sex with a new person I was a virgin when I met my wife I was 18 and she was 20. But our sex is more like 30min-1hour right from the very beginning. <br>I am worried about will we be compatible with anyone else other than our spouses? <br>Am I doing something wrong?<br>We have a great sex life and I don't have any ED right now and I don't want to lose her.
