Had sex for the first time... now when i pee it smells like rotten eggs

I lost my virginity a few days ago and my now whenever i pee it smells like rotten eggs. Im super worried and I can’t talk to my mom about it as she believes in sex after marriage so she’l be super disappointed. We used a condom and he still pulled out and i peed before and after sex. It also lasted like 5 minutes so i dont know what it could be??
