Dear Yvonne,
Are men’s nipples really that sensitive? I wouldn’t think so. What would make them so?
—Brad

Dear Brad,
In both men and women, the nipples are surrounded by the areola and consist of smooth muscle fibers that cause them to become erect, (like when cold or sexually excited). During sexual stimulation, the nipples fill with blood, becoming more sensitive to the touch in some individuals; male or female.

Dear Yvonne,
Are men more interested in sex than women?
—Manny

Dear Manny,
Though this is the general thought, it’s not the general rule, as many women would contest. The idea that men have a stronger sex drive and more sexual interest than women is largely due to society traditionally having been more permission-giving with the male libido and pursuits. The true difference lies in when the sexes are interested in sex.

A woman’s sex drive is related to her menstrual cycle. For many women, it’s heightened during ovulation whereas for others it’s the week she’s menstruating. For males, his sex drive varies more daily versus monthly, and is dependent upon testosterone levels. A male’s testosterone levels tend to be highest in the morning.

Dear Doc,
When we hear about people being attracted to another’s feet, for example, the foot fetish, it always seems to be men who are into them. Do women, in general, find men’s feet sexually attractive?
—Bill

Dear Bill,
In general, there’s the stereotype that men’s feet aren’t attractive, especially if he’s past a certain age, and that men’s feet smell in large part because of a lack of attention. While your average female is not expecting him to become a metrosexual with the regular pedicure, or to have attractive feet per se, her biggest expectation/hope is that he will keep them clean. She wants him to wash them with warm soap and water, to trim his toenails and clean under them, and to make efforts to reduce dirt and the chance of fungal infections.

That said, women do notice men’s feet, but are usually more caught up in gauging his facial expressions and other body language when it comes to reading his potential attraction/feelings for her. Unkempt feet aren’t a dealbreaker for most, as she’ll excuse that he’s “just being a guy,” and add it to her mental checklist of things to touch up about him as they get more serious.

Are men’s nipples really that sensitive?  I wouldn’t think so.  What would make them so? -Brad

Dear Brad,
The sensitivity of a person’s nipples is very individual, regardless of a person’s sex. Both men and women may have nipples that are incredibly sensitive or that have no erotic response whatsoever. This gender similarity is due to the fact that the nipples of both men and women are surrounded by smooth muscle fibers that cause them to become erect, e.g., when aroused or cold. When stimulated, they fill with blood, becoming even more sensitive for some people.

While the stereotype is that men cannot have sensitive nipples, some men beg to differ. Many of them have nipples that are actually more sensitive than those of their female counterparts. Many of them enjoy nipple stimulation.

A new kind of men’s underwear is being designed to pick up information about arterial blood flow and blood pressure, reported London’s Daily Mail.

The underwear has at least four sensors in the waistband and would determine how fast blood is flowing through the arteries, according to the newspaper.

The technology would not work as well in women’s underwear because the waistbands would be too thin to accommodate the equipment.

Australian researchers say the same gene that puts women at a high risk for breast cancer also may give men a heightened risk for prostate cancer.

Men from families where the women have high rates of breast cancer are about four times more likely to develop prostate cancer, according to research funded by Australia’s National Breast Cancer Foundation and conducted by kConFab, an Australian and New Zealand consortium for research into familial breast cancer.

Artificial human sperm could come to the aid of infertile men, according to a team of scientists who have used lab-grown sperm to inseminate female mice.

Artificial sperm could also make males totally redundant, permitting women to give birth without a biological male mate.

What is your opinion?
