Yes. Totally. I am older now, but when I was in a relationship in my early 20's, I asked my serious boyfriend if we could have a third pary- a girl. My fantasy was basically kissing the girl and having her service me, then both me and her going down on him at the same time. They I wanted both of them to service me. No anal. Def oral and Vaginal to be involved. But my boyfriend did not want to for fear of it tearing us apart.
