Heather Graham is a sexy, 43-year old actress. And, Heather Graham has no difficulty putting her age in perspective.

In an interview with Vegas magazine, Graham, starring in the upcoming film, "The Hangover Part 3" opens up about sex, marriage, and what it takes to look like she does.

"I was taught to be demure," Graham told Vegas. Graham says she was brought up in a strict Catholic family, "so it was harder for me to learn how to stand up for myself and go, 'What do I want? What are my desires?'"

According to Vegas Magazine, Graham has dated some of show business' most eligible bachelors, includin Edward Burns, James Woods, Matt Dillon, Kyle MacLachlan, Leonardo DiCaprio, Benicio Del Toro, Russell Crowe, Scott Speedman, Matthew Perry, Adam Ant and most recently Jason Silva.

"I do have some great stories; I've definitely lived. ... Maybe [I will tell them] when I'm 80, and everyone's dead," she said. "I'm not against marriage. I would definitely do it if I was in the right situation. I would like to be with someone I could settle down with and be with for the rest of my life. But I don't feel like I need to. ... I kind of feel like I dodged a bullet. I'd rather be happily single than unhappily married. In the meantime, I'm having a lot of fun. Good sex!"

As for her fantastic figure, Graham credits Pilates and yoga. And despite growing older in front of the cameras, Graham says she doesn't feel the need to nip and tuck and plans to age naturally.

"I have not ever opted to do surgery, because it's scary," she tells the magazine. "Maybe some people get it done and you can't tell and that's great, but I feel like it makes your face look weird. I think if you're happy, then that's the glow."
