Doctor reveals the body part visible to everyone that exposes the size of someone's penis

A surgeon and sexual health expert has revealed the body part visible to everyone that exposes the size of someone's penis.

There has long been believe that looking at an individual's hands and feet indicate the size of a man's manhood.

However, the idea is very much an age-old tale, and it's apparently another body part that indicates how big or small a man's penis is.

Dr. Rena Malik appeared on the Diary of a CEO podcast earlier this year, where she put to bed rumors lads with bigger feet have a bigger penis.

However, the surgeon explained how there is another body part that could link to the size of one's manhood.

"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 was that nose length was correlated with penile length, not hand length or foot," she explained.

The expert didn't go further on whether she has seen or even been involved in studies linking nose and penis size, though she did say to have seen an increase in man concerned about the size of their penis.

Malik said that a survey done with 50,000 heterosexual men found 45 percent were unhappy with the way their penis looks.

Despite that, 85 percent of their partners said they were ‘satisfied’ with the size of their willies.

Elsewhere in the interview with podcast host Steven Bartlett, Malik spoke about how much sex a couple should be having.

She said: "There's no ideal number, but when you look at studies which have looked at large numbers of people, people who are in partnered relationships are having sex about once a week on average.

"If they're in partnered relationships where sex is always available, but it's so variable person to person.

"What I really like to say is it's not the quantity of sex that matters, it's the quality of sex.

"If you're having good sex once a month that may be sufficient for you rather than having mediocre of 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.'"
