It may surprise you to learn which body area can provide some indication of the size of someone’s, erm, private bits, according to a sexual health expert.

Without a question, it’s a sensitive subject.

Numerous studies on penis size have been conducted, however their accuracy depends on how truthful the participants were.

However, a doctor has been discussing the one visible bodily feature that appears to reflect the size of a person’s penis for a perhaps more precise reading.

Many people think that a person’s hands and feet reveal how big their manhood is, however that is a very ancient story.

Earlier this year, Dr. Rena Malik corrected the record on the Diary of a CEO podcast, asserting that it is a different bodily component that is directly related to penis size.

“There’s one study — it’s a Japanese study where they looked at only Japanese men so there are some limitations — but they measured all these body parts and penile length and they found that nose length was correlated with penile length, not hand length or foot,” she said.

The expert claimed to have observed a rise in males who were worried about the size of their penis, but she did not elaborate on whether she had seen or even participated in research that linked nose and penis size.

According to a poll of 50,000 heterosexual guys, 45 percent of them were dissatisfied with the appearance of their penis, Malik continued.

On the podcast hosted by Steven Bartlett, the conversation revolved around sex, and Malik also touched on the appropriate amount of sex for a couple.

“There is no ideal number, but studies that have examined large numbers of people show that people in partnered relationships are on average having sex once a week,” she added.

“Sex is always available in linked relationships, but it varies greatly from person to person.

“I really like to stress that the quality of sex is more important than the quantity.

“If you’re having good sex once a month that may be sufficient for you rather than having mediocre or bad sex four times a month, or 10 times a month even.

“Ultimately there’s no right number, it’s really what’s right for you and I think focusing on some benchmark of sex is actually harmful because now you’re like ‘I need to have sex this many times’.”
