Molosser breeds that are not same-sex aggressive?

I want something muscular like a Pit Bull, but not same-sex aggressive. But I don't want any fragile dogs like French Bulldogs. I also don't want Newfoundlands, Bull Terriers, Rottweilers or Great Danes. I want a dog that gets a long with other pets and is medium to large in size, and doesn't drool a huge amount like the St. Bernard.
