I always love hearing celebs tips when it comes to keeping a Hollywood marriage lasting. When asked in the past Will and Jada always chalked it up to allowing each other to have "crushes" on other people and even telling each other about it. This didn't exclude fantasizing.
“Our perspective is, you don’t avoid what’s natural and you’re going to be attracted to people.” he says.
“And if it came down to it, then one would say to the other: ‘Look, I need to have sex with somebody. Now, I’m not going to if you don’t approve of it’.”
The 39-year-old star explains that the couple’s open policy has been in place from day one of their 10-year marriage.
“In our marriage vows, we didn’t say ‘forsaking all others’. We said ‘you will never hear I did something afterwards’. Because if that happens the relationship is destroyed.”
Other things that Will says are important in his relationship are keeping in shape for his “little firecracker” Jada, the “look in her eyes”, and communication.
