What should I do if I meet a boyfriend who is not as active as myself in sex? I think men are very active.

Boys are indeed more active in sex than girls, but they are also influenced by age and illness. Under normal circumstances, boys will definitely take the initiative, but your boyfriend may be too tired to take the initiative, or he may have a shadow because you refused too much in the past and didn't want to take the initiative to bring it up. The last one may be a recessive disease, which may be genetic. You can go to the hospital for examination at your convenience. Anyway, you should trust your boyfriend and support him.
