Why does semen taste bad?

A moment’s reflection gives the answer.

Natural selection maintains the repugnant taste of semen so that a man’s sperm will wind up in the appropriate place: the vagina and not the stomach. So long as sperm tastes bad, women will not be tempted to swallow it, but will turn their male partner towards conventional intercourse, which of course is the only act that will produce children. In other words, any male with good-tasting sperm would have fewer offspring than his competitors. A man whose sperm tasted like honey would probably not have any children at all.

What does the skeptical community make of this?

It's on pharyngula too.


My first thought was why there's the patent assumption that semen universally tastes bad... I know a few people who like the taste. 

That or they were lying to me...

I'm skeptical, I think even if men had spunk that tasted like chocolate woman would get pregnant at the same or very close to the same rate. 
1. I don't think both parties would want just oral all the time
2.  I don't think taste alone is why many people find swallowing sperm gross.
3. The taste of semen has nothing to do with woman's maternal clock and desire for vaginal intercourse.

While it would be great if all woman loved to swallow or men had great tasting juices I don't think it would have that great of an effect on our evolution.  Many woman still like to bang and still want babies. Seman taste bad because it was not designed to tasted good. Taste from different people very mainly on diet and life style.

Don't women have a different idea about whether it tastes bad?

Some of you have got it all backwards. Tings don't evolve to taste good, the brain evolved to make us like things that high on energy, therefore making it sweet. There is nothing inherently sweet about sugar for example. Sugar taste sweet because it is high on energy which is good. Btw. taste is mostly something you learn. Just think of people who like cheese with mold or "thousand-year egg" etc.

That was probably not very well written, but you got the gist of it.

I have known women who didn't think that it tasted bad. Maybe it is an acquired taste?

Any women out there who can help out?

Exactly! The whole premise of the question is wrong. Why semen taste bad is not a good question. Why some women might feel it taste bad, could be because they had a bad experience or something. I don't know what semen taste like, but i would guess that it's more the texture they disslike, than the taste.

Why would it taste good?  As mentioned before, generally we have evolved to like things that are good for us or high in calories and dislike things that are bad for us, bitter usually means poisonous.  There is no evolutionary advantage to anyone liking the taste of sperm so no real reason for us to like the taste.

One further thought. The human tongue only senses about 4 tastes, the rest is smell. So, as stated above, there wouldn't be any evolutionary pressure to acquire a 'taste' for semen, and any taste would be related to other tastes.

If all of your exposures to the taste of semen are pleasurable, you would acquire a taste for it.

Yeah, saw it on Pharyngula as well.  I think don't think the intent was for people to take it all that seriously.

And re the comment from  Sirdrinkalot, who probably should avoid posting in this thread, if you know what I mean, he's probably closer to the truth.  Sugar is sweet because it tastes good, not the other way around.    (and it tastes good because it is a high energy food)

I'll throw it out there and say that the taste of the subject matter of this thread is not selected for.  But drinking things with a similar taste or texture probably is selected for.   

Hmm, next time I get into a pissing contest with one of those kangen water people, I'm going to throw this in their face.  If drinking their alkaline water is so great, how come semen tastes so bad?  Or are they suggesting it would be healthy for people to do more of that?  Maybe I'll bring my wife with me when I have this conversation.

Being a woman who has tasted semen from different (tested) partners I can tell you from experience that the taste of semen varies from man to man. I believe that changes in a man's diet can also cause changes in the taste of the semen.  It's a bodily fluid and is therefore subject to all the complex chemistry that goes with all bodily fluids.

Also considering the number of STDs that can be transmitted orally I can see an argument for evolutionary advantage in not swallowing and therefore developing the "bad" taste. But isn't liking a taste subjective anyway?

a. It has a lot of fructose in it.

b. I don't think it changes so much from diet but from the mentality of the man at the moment of intercourse. If you cum when your with a slut doing kinky stuff it will be different from when you cum from romantic long-lasting sexual intercourse with a long-term partner.

c. I think I recall from The Naked Ape that it is a normal phenomenon for human females to give their partners oral sex.

d. It could be argued that a man would be turned on by a felacious (sp?) woman and thus her chances are greater for baring his offspring.

e. What's with the porn these days? I'm surprised some of these girls don't suffer from habitual jaw dislocations. What ever happened to the gag reflex? (perhaps this topic should be moved to explicit....)

A gay male told me that the taste varies a fair bit based on the food consumed. I don't know the time lag between consumption and ... consumption.

Without getting too EXPLICIT, the taste of a woman varies from woman to woman and seems to vary with diet as well. I know more about this than my previous post, which was second hand. I had a girlfriend who was hypoglycemic. She didn't consume any added sucrose. And the taste was different.
