Playboy.com: Which question is the dumbest you've ever gotten?

The Playboy Advisor: It takes quite a bit for the Advisor to consider any question truly dumb, especially given the quality of sex education these days. But it takes true chutzpah to believe that we will supply you with the address and phone number of the woman who wrote to say that she isn't sure how to ask a man for anal sex. A few years ago a reader from Idaho asked, "When you are moving in to kiss a girl, which is the proper way to tilt your head?" That may appear at first glance to be a dumb question, but is it? We dug deeper and found a study by a psychologist in Germany who spied on 124 kissing couples and found that 65 percent tilted their heads to the right. So there you have it -- science triumphs again, and the Advisor has a little fun.

Playboy.com: Smartest?

The Playboy Advisor: The smartest letters are usually from people who are disagreeing with a response, or expanding on it, which is great, because the column is meant to be a discussion rather than a soapbox. We have learned a great deal from readers over the years.

Playboy.com: Funniest?

The Playboy Advisor: When a journalist asks Dr. Ruth this question she often tells the story of the woman who would try to toss onion rings onto her husband's erection. My onion-ring story is the guy in Florida who wrote to say that he liked to drag a recliner into the woods and sit in it naked after spraying bug spray all over himself except for his genitals. He wanted to know if that was normal. Another was from a guy who got turned on when his wife pretended to be a hooker but didn't like the fact that she kept the $30 he gave her during the role-playing. He wondered if that made her a real hooker. We assured him that she would need to have more than just him as a client to be a prostitute.

Playboy.com:
Most common?

The Playboy Advisor: The most common letter is from men or women in committed relationships who aren't getting as much sex as they'd like. I get the sense from most of these letters that the writer really loves and cares for his or her partner but just doesn't know what else to do. One psychologist has called this phenomenon the "sex-starved marriage." These questions are difficult to answer because there is probably much more going on in the relationship than can be explained in a letter, or even that the writer may be aware of.

Playboy.com:
Least common?

The Playboy Advisor: Whenever I get a letter from a reader who has a fetish that I have never heard of -- and this still happens nearly every month, even after 12 years -- and I do an online search to see what's out there, I am no longer surprised when I find at least one website devoted to the subject. The latest example would be guys who become aroused watching women pick their noses.

Playboy.com: Hardest to answer?

The Playboy Advisor: The questions about sexually transmitted diseases, including HIV, are always a challenge. We want to provide good information and urge caution but also not cause undue concern. People must evaluate the risks based on their own situation, and we can only provide the information for them to make prudent decisions.

Playboy.com: Most technical?

The Playboy Advisor: That's easy -- anything having to do with electronics or automobiles. They usually cause the most controversy, because everyone who knows about the topic is guaranteed to triumphantly note that we didn't mention this or that particular detail about the ohmometer's gigaband oscillator.

Playboy.com: Most disturbing?

The Playboy Advisor: The book contains the first lines of a dozen letters that we didn't answer in the magazine, for reasons that will be obvious. The most disturbing is probably the woman who had gotten pregnant by her college-age son. She wanted advice on how to tell her husband.

Playboy.com: Sexiest?

The Playboy Advisor: There is usually one letter each month that makes me shift in my seat. Typically it is from a woman describing a particularly hot threesome or an unforgettable encounter under a blanket on a long airplane trip, etc. The question is usually, "Should I do it again?" Now, that's a dumb question.
