Is something wrong with my husband

My husband can only ever go one round of sex. I’ve always dreamt of being able to go round after round of sex, kinda like in the movies lol. But as soon as he gets off he’s almost instantaneously soft. I’m just getting geared up and he’s completely done. If I try to initiate more he kinda just pushes me away. If we have sex in the morning he’s totally not into having sex again later in the day. Plus he always falls asleep almost right after. What can I do? We’ve been married 5 years, and he was a virgin for our wedding night ( best 30 seconds of my life) lmao. Is it that he doesn’t find me sexually attractive anymore and therefore can’t bring himself to making love to me more than once? Help!
