As a general rule, keep dirty talk simple and personal: Pick a body part and tell her how sexy you think it is, or describe a fantasy you have involving her. That's why we asked sex and relationship experts for their best advice and foreplay tips for making the most of perhaps the most important part of sex. Do it right, and you'll prime your partner for an incredible orgasm. With the rougher top side of the tongue, flick from right to left and then up and down. Try to mix up your tongue play with the occasional closed-mouth kiss on her nose, eyes, and forehead. There are plenty of ways to expand your oral sex repertoire, and you should always be looking to add new moves and mix things up. Still, many men do wrong by it. If sending nudes is something that turns your partner on, go ahead and swap some sexy photos with one another.
