How can I get him to last longer?

Adi

Me and my boyfriend had sex for the first time last week. Now I don’t expect him to last more than a few minutes (he’s an 18 year old boy, and I’m also 18) but he only lasted for a few seconds. How can I see to it that he lasts longer in bed so I can get pleasure out of it too? Do you think he was just excited to be taking my virginity and I was really tight? (He barely fit inside me)
