I have to agree with a lot of what Ruby, subwife, and IDCrewDawg said.
Every time we have 'vanilla' sex it is never without D/s elements, like IDCrewDawg said. Whether it is the way he handles me or just him commanding me, it is always apparent that he is in control. And yes, usually BDSM activities lead to sex for us, but not always. Well, some type of sex is had, but not always intercourse if that's what you mean.
To get in the mood though all I need is him, and any way I can please him is pleasing to me, whether he wants something 'normal' or something more intense. Hope that helps.
