Often, when I drink coffee, I get an erection.  Does this happen to anyone else?

Caffeine is a central nervous system stimulant which causes nerves to be excited all over your body (hence the awake and wired feeling it gives you) so yes, getting an erection from caffeine or coffee is most likely normal.  But if it's bothersome consult your physician!  Hope this helps!

many reasons it could be cause you are thinking of something that turns you on such as porn,girls,mastu**tion,sex or someone said something that made your brain subconsciously think about and your penis erects,it is perfectly normal.it happens to me all the time

Erections can happen at any time for no apparent reasons especially in adolescents. I remember when I was a youngster just entering puberty it was happening to me every five minutes. Very embarassing.

Coffee is a stimulant and irritant first of all. when you drink coffee and you haven't eaten anything before, your body perceives as food and the digestion starts leading to you wanting to go the 'toilette'. apart from that, if you add milk or cream and you intolerance this is what is causing it. if not, it's the first thing that i mentioned. you can switch to homeopathic coffee named CARO by NESTLE (available in most health stores or pharmacies). personally, i like it and it doesn't contain caffeine.

Is it from drinking to much?  Or could you have a medical problem?  Enlarged prostrate can cause that.  Get checked out!

forget about them.\n\nAnd no I am not being funny here, it is true. The more you think about sex, your penis, or getting erect, the more it will happen. Even if you aren;pt gay, just thinking about a freind popping one can get yours to rise to an embarassing occasion.\n\nFirst off, erections are as normal as water. They happen at random times, they don't happen sometimes when you want them, they occur about every 45 minutes while you sleep, you usually wake up with one every morning, and they always seem to happen right when you are called upon in class to stand up.\n\nSo, the best remedy is to simply face the fact that yoru penis will do what it pleases and you might as well get used to people noticing and don't waste time getting embarassed, trying to hide them or otherwise willing them to go away. Simply carry on with your normal activities as if they never occur and they will reduce in both frequency and in duration.\n\nOh, and a daily masturbation sessions wouldn't hurt either to keep you happy and little things satisfied.

There is a power drain when you get an erection.  This power drain takes a little time to build back up.  It is during these times when you see guys cutting fingers off with power tools, answering those stupid questions like "do i look fat in this", and talking incoherently when a women with nice totties and back side walks by!

It’s a normal thing that generally occurs to anybody when sleeping and precisely during the “dream” phase of the sleep called REM (just at the end of the sleep-time).\nGenerally they are hot dreams that we don’t remember when awake. Of course younger the subject is and longer and stiffer the erections are. Ok?\n(My God how many silliness I read as answers here!)

it could be PMS or your diet, have you had a lot of caffeine lately? Has anyone sucked on them too hard? (sorry to detailed) but that usually happens...I don't think it's a yeast infection

sounds like a question I had in high school always fearing an erection at the wrong time.  two simple words will help you though most obsessive thoughts, f**k it ( not literally in this sense but you know what I mean)

Another reason could be you have simply had too much caffeine and/or not enough sleep.  If I drink too much coffee and eat chocolate, my eye twitches.

A couple of Bud Lights usually gives me an erection.  I agree with the hair thing.  I trimmed mine and it looked like I gained another inch.

oh, my brother, coffee is a wonderful thing. it speeds up yer metabolism, increases blood pressure, heart rate, and sharpens yer focus. but-that's if you exercise moderation. too much can make ya irritable and nervous. so-to drink or not to drink? baby, drink  ON, man!

Your problem is the drinking.  You would not have mentioned it if it was not often. At 18 getting cozy with getting blasted is a sign of alcoholism - at least in your near future.  That is the problem.  Your penis is telling you that it, too, is drunk and it is hard to get hard when it doesn't know which way is up.  Also, the reason you can't get it up on occasion when you are about to get laid is because you need a drink so bad that your concentration goes to the booze, not the boozy broad you are about to do even though she is a sad sack herself.  So, do your penis a favor and stop the flow of blood alcohol to the head so that it won't have a hang, you should excuse the expression, over when it has to go to work.  Instead, pour some not so hot coffee on it when it is expected to perform.

Oh, I thought you were referring to erections. Never mind.
