Before we get to positioning, it could be that you’re using too much lube and it’s turning your lady parts into a sexual Slip’n Slide. (We know the bottles can be big, but about a teaspoon should do). Now that that’s out of the way, go for the X Marks the Spot move from Sex Positionsforeverybody, by sexologist Jill Mcdevitt, PHD. In this awesome twist on missionary, lie on your back near the foot of the bed with your legs straight in the air. Cross your legs at your knees to make an X while your partner stands on the floor and enters you, holding your legs for leverage. “It’s a snug position for him that also makes you feel tight,” says Mcdevitt. It also works well with guys who are more toward the teeny-weeny end of the spectrum. Best of all, you’ll both be super into it.
