It might depend on how much my partner and I know each other. When I first started dating my now husband, I’d be more likely to drive the vibe myself when getting to the end. Now, though, he knows my body well enough to do it himself, and I have better orgasms for it. When I’m not the one directing the vibrator it makes it a more heightened experience for me, since I don’t necessarily know everything he’s going to do.
