Is 24 too many?

My bf has had 24 sexual partners. This is only counting the ones who engaged in penetrative intercourse, not just oral or fooling around. He was 16 when he lost his V and he's 26 now. I know 10 years is a long time, but I lost my V at 15, I'm 24 now and have only had 3 partners. It's not that I'm jealous, but it makes me feel strange to be on such a long list...
