Games Workshop made sure to shy away from actual sexuality(not the models clother/armor though), and go All-in on violence, as it's "Meant to appeal to kids and teenagers"(not really) but in america sexuality is taboo... So most people associate it more with violence and gore than sex... And GW is also HIGHLY PROTECTIVE of their IP, with TONS of Cease & Desist being issued, so most people would rather not bother with it, or risk having their legal department knocking on their doorstep...
So, other than inquisitor trainer, haven't found anything decent game-wise(if you go to rule34, there is some nice artwork around though...).
