Men's multiple O's

So I've heard that only women can have multiple orgasms. For the longest time I though it was true until one night my SO and I were having sex and he came twice. Afterwards I asked him if he did indeed cum twice and he said yes. I was then like "I didn't even know that could happen." And he just said "me neither" 😂 I was so proud of myself, like I guess I'm just magical. It hasn't happened since then but I try all the time. Has anyone else given their man multiple orgasms? If so, is there a special trick?
