Ashley Graham keeps her 8-year marriage fresh with lots of sex

Ashley Graham and husband Justin Ervin have figured out the secret to a successful marriage.

“Just have sex!” the supermodel told Elle.

Graham, 31, and Ervin, 29, have been married eight years.

“Have sex all the time,” she elaborated. “Even if you don’t feel like it, just have sex. I have found that if we haven’t had sex, we get snippy, and then if we are having sex, we’re all over each other. For us it’s like, ‘Oh, let’s have sex.’ And then we’re just right back in a great mood.”

The couple famously waited to have sex until they were married. “I slept with half of New York City. I had done it all, literally!” Graham said of their decision to wait as she felt she moved too fast with other guys.

“Something that it did for us was build up our friendship, and it also built up our trust and communication,” Graham added.

Graham said prior to consummating their marriage that they engaged in heavy make-out sessions – which even involved tossing her into different sexual positions – but sex wasn’t her true focus.

“I wasn’t worried about, what’s sex gonna be like with him? It was more, do I trust him?” she pondered. “Is he someone I want to be with for the rest of my life?”
