I only somewhat know Red River out of the three you listed, and, yeah, it's pretty heavy on the sexual themes and violence. It's not just sex and gore, though, it's based roughly on actual ancient history, and I found the characters quite interesting. I haven't had a chance to read a lot of the volumes, but I thought the ones I could get my hands on were well done, and it approaches its subject matter in context. There's a war going on and lots of political intrigue, hence the violence. In those days, it was a given that royalty (particularly the higher-up males) would sleep around a bit and have concubines, etc., hence the sexual themes.
Also related to the time period, there are plenty of references to heathen gods, as that was what that nation believed at the time. One villain also practices dark magic.
Really, it's up to you if you want to read it. It's not gratuitous, but there is a lot of potentially objectionable content.
