Would they rather have the music on or off? Comfort with a new partner often takes time and communication, and that goes for both men and women. Want to get the hottest sex positions, the wildest confessions, and the steamiest secrets right to your inbox?

Don't just go along with something—make sure you're excited about it. Need some guidance to get you started? They should take that as their cue to be even more communicative with you.
