from www.complex.com – When you want the best advice, it’s a good idea to consult somebody who’s seen a lot. And although she’s only 20 years old, we think Lupe Fuentes qualifies. After making a series of videos in her native Spain (and coming to the rescue of a man accused of possessing child pornography for owning some of her work), the diminutive Colombian-Spanish stunner moved to the U.S. and signed with Teravision as a contract actress last year. Turns out homegirl is the sickest Spanish import since Chris Columbus and his small pox blankets.

Needless to say, the 2010 AVN Best New Web Starlet has caught our, er, eye. But when she visited the office last week, we found out she’s a real down-to-earth girl, with a surprising amount of real world wisdom to offer (most of which involves having more sex). So we decided to have her be our debut columnist in a new feature, the Complex Porn Star Ethicist. After the jump check out the advice she gave to a couple “hard up” readers, and peruse a gallery of pictures we took of her on the streets of New York. And be sure to check in next week when Lupe answers more readers’ queries, and send in your own vexing dilemmas to [email protected].

My girlfriend of five years just broke up with me two weeks ago, and I know her sister is down to get down. How long do I have to wait to jump to little sis? Remember she broke up with me. —“Ready to Do The Mom Next,” Charlotte, North Carolina

LUPE SAYS: “Dear RTDTMN, Depends why she broke up with you. If she’s a fucking bitch, go ahead right now. Go ahead right now. If it was something like you hurt her feelings, or something happened that is your fault, you have to wait like…two months? Go for the little sister, enjoy! Life is short.”

I want to ask my girl to be in a threesome, but not the kind most guys think of. We’ve been together six months now, and I think she’d be up for it, particularly if she’s drunk, and I’m pretty damn sure we could find a guy willing to take part. Am I gonna regret this? —“Double Stuff Is My Favorite Cookie,” Sparks, Nevada

LUPE SAYS: “Dear DSIMFC, Personally, I always have threesomes, but I think in normal relationships, you have to be really careful with your girlfriend or boyfriend. Normal people that’s not porno stars or nothing like that, they do threesomes with other people that is not their girlfriend or boyfriend because nobody can hurt your feelings. But if you really want to have a threesome with your girlfriend and another guy, just think that it is just sex. This is nothing about feelings, this is bodies, like meat. You have to have sex like you have to eat. She don’t love him, she don’t want to be with him, she is not thinking of him, it is just that moment. After this, it’s like nothing happened.”

Apparently I have a really funny “fuck face.” Reason I know this is because now three different chicks have actually started laughing when I came. I don’t think it’s a “performance issue” as I last pretty long and all, but it is a big turnoff for me (obviously) to be laughed at during sex. Any help on how I could change that? —”Stan Ipcus Got Nothing on Me” Santa Rosa, California

LUPE SAYS: “Dear SIGNOM, Depends what girl you are fucking, you know? If you fucking your girlfriend and she laughing? Just change that face. If it’s other girls? Fuck that bitch. Fuck that bitch, it’s only one time!”
