Title: Is giving oral sex fattening?
Post by: John Chapman on 23/02/2009 23:30:52
My wife once refused to give me oral sex on the grounds that she was on a diet! I tried to tell her that all that bobbing up and down would burn off more calories than she would consume and she replied "not in 5 seconds, Mr Trigger Happy". But enough of that. Anyway, I won the argument and her last words were "mmph hnnm wommn arn hmmmf", which I hoped translated to "I love giving you pleasure, my Darling" but turned out to be "See what sharp teeth I have, you lying bastard". So my question is this:

Does giving oral sex result in a nett loss or gain of calories? (https://www.thenakedscientists.com/forum/proxy.php?request=http%3A%2F%2Fbestsmileys.com%2Fblushing%2F3.gif&hash=b2efec13ed2f00af79837ba48ae5d07e)

Now I know there are huge variables such as 'bobbing' distance (ie penis length), weight of the woman (or guy), size of ejaculation, length of time guy manages to hold on, etc. But is there anyone out there who can do a back-of-the-envelope calculation and give me a rough idea based on typical likely measurements? Any volunteers for some empirical research? Mr Chem4me, You're always up for some home experimentation. Tell Mrs Chem4me it's all in the name of science.

Lets assume the woman weighs 8 stones (50 kilos, 112 lbs) and she lifts half her body weight (ie from waist up). I'm assuming the lift height is unimportant on the grounds that the longer the strokes the fewer strokes per minute but that she is lifting her weight for half the time (ie on the upstroke but not the downstroke). I've got no idea how to find the calorific value of an ejaculation but we could approximate the quantity to be about a teaspoon typically. So over to you, clever people in Naked Scientist land.....

What I am hoping for is an estimate of how many minutes it would take to burn off the calories my wife is about to consume. I'm hoping to be able to tell her 'just another 45 minutes or you'll get fat' or even better 'just a couple more hours!' Or what about 'If you can just keep going til Monday morning....!'

The average ejaculate, laden with between 200 and 300 million sperm, amounts to about about 5 calories.

These are derived from protein, including enzymes, and sugars (mainly fructose) secreted into semen by the prostate gland to provide the sperm with the energy to swim.

Other 'ingredients' present in semen include :

Water
Vitamin C
Citric acid
Phosphate and bicarbonates, to regulate acidity 
Zinc
Prostaglandins

For comparison, a greasy cheeseburger contains over 500 calories, so to equal one junk-food attack you'd need to gulp down over 100 ejaculates. Comforting thought...

Hi Chem4me

Brilliant. You've found the missing piece of the jigsaw. Now all we need is for someone to crunch the numbers. and put the jigsaw together.

I knew you'd come up with something good. I'm a little disappointed that my question isn't entirely original, though. It seems like I'm not the only person obsessed with sex.  [::)]

Intriguing question but I always thought that oral sex was like lobster thermidor - you don't get it at home. [;D]

That's exactly what I tried to tell my wife. Unfortunately she's not as gullible as you! lol.

Why do you say it's slimming?

That's right mate. Us guys have got to stick together.

We should tell these women it makes them look younger too. And tones their bodies.

I emailed this question to the Naked Scientist team and got a quick reply from the guru of science himself, Chris. Thanks for that, Chris.

He says,



"Dear John

I think that the energy expended in obtaining the "nourishment" outweighs the calories derived through its digestion...at least for a human ejaculation. Bulls, boars and whales...well that's a different story.

C"

So there we have it, ladies. The more oral sex you give us guys, the thinner you'll get. I've always told my wife she doesn't need to diet and is perfect the way she is. I realise now that this is very unsupportive and in future will help her burn off those calories. I'll tell her 'Chris said so!"

Probably a wise decision Neil. Not only from your point of view, but most certainly from the point of view of your long suffering neighbour.

You guys had to mention it having a slimming effect. I don't know if this is factual or not but I read that a person who performs oral sex on a man at least 3 times a week for at least 10 minutes per session over a couple of months time would have a slimmer looking facial appearance because the muscles used would help to tighten up the cheeks and chin.

Hmmm!

I shall be off to the Dragons Den to seek funding for my new business venture.

I have a slogan already:

"Why bother with Botox when you can have more fun with Bollo(https://www.thenakedscientists.com/forum/proxy.php?request=http%3A%2F%2Fbestsmileys.com%2Fmouthzippedshut%2F1.gif&hash=037747c4bf0ab86db4337375f3c71610)!"

Maybe my slogan needs a little more thought.
