Position of the week: T-Junction
Is he on the larger side? This position allows the depth of penetration to be controlled for comfort and pleasure.
He penetrates from behind. Keeping her legs straight and together, she moves them forward so they're angled away.
His hands are free to stimulate her breasts and clitoris. The more turned on she is, the more expanded and lubricated she'll be.
Penetration is easier if she bears down (like she's pushing something out) with her vaginal muscles. Try grinding against each other, rather than thrusting.
Make it even better…
Here we refer to a heterosexual couple but the same position can be adapted for lesbian couples with the use of a strap-on dildo. It's also a great position to try for anal sex (and add a male masturbator into the mix if the receiver has a penis).
