I get a similar experience as Nyx890. I've just started using Devious Desires yesterday for the first time and have only tried the masturbation interaction. The masturbate on any object will cause my sim to walk up to the object, T-pose, then begin the animation with no problem. I have not seen a T-Pose after the masturbation sequence runs its length or any other issues with that particular animation. I will do more testing and let you know what I find in cased it helps.
