An erection is the stiffening and rising of the penis, which occurs in the sexually aroused male, though it can also happen in non-sexual situations. The primary physiological mechanism that brings about erection is the autonomic dilation of arteries supplying blood to the penis, which allows more blood to fill the three spongy erectile tissue chambers in the penis, causing it to lengthen and stiffen. The now engorged erectile tissue presses against and constricts the veins that carry blood away from the penis. More blood enters the penis than leaves until an equilibrium is reached (equal volume of blood flowing into the dilated arteries and out of the constricted veins). A constant erectile size is achieved at equilibrium.\n\nErection facilitates sexual intercourse though it is not essential for some other sexual activities. Although many erect penises point upwards, it is common and normal for the erect penis to point nearly vertically upwards or nearly vertically downwards, depending on the tension of the suspensory ligament that holds it in position. Stiffness or erectile angle also varies.

because they make you horny and men used to say they had blue balls when they were aroused but not relieved.  When men are horny or erect for a long time, with out ejaculating a slight blue purple color appears on their penises but it is harmless.

Well, one answer could be that during masturbation, you are being a bit rough on the testicles.  Is it possible that your stroking is causing either\na) your hand to contact the testicles repeatedly\nor\nb) your testicles to bounce around a lot and thus be banging against yoru body.\n\nTry this:\nNext time you masturbate, use one hand for the stroking and wrap your other hand around your balls sort of like a cup athletes wear to protect their testicles. Don't hold them too tightly; just fondle them gently and keep them from being hit or bouncing around. I suspect this is not only goign to feel good but may well eliminate the after masturbation pain you have been experiencing.

happens to me too.. it might be to rough.. if so tell him to take it slow... it could cause irritation. uhhh... you dont have to say hes good in bed... he might not be.. being to rough is not always good sex if it hurts its not right. there most likely isent anything wrong with you... im with the same guy it feels great its not rough and i love every second of it... i love the feeling if it gets rough but i know when it gets too rough and it needs to slow down.. make sure communication is very clear between the two of you.... most girls bleed... and the first time you have sex you dont always pop your cherry. you finally poped your cherry and if you dont have sex for long periods of time your vagina goes back to place making you tight all over again.

It takes awhile for the blood to exit the penis and go soft again. Don't think you're wonderwoman it happens in every guy. Takes about 5 minutes sometimes longer if she cuddles with you and your tall tommy is rubbing her hips. I need to go jerk off

A guy does not need to be hard in order to experiance pleasure, or to have an orgasm.  A guy DOES need to be hard to penitrate a vagina, but I have gone down on several guys who were not able to get it up, and they were still able to orgasm, ejaculate, and all of them reported enjoying themselves - despite being flacid.\n\nAnd the seemen is just as much fun from a soft guy as from a hard one.\n\nin fact sucking a soft penis is a diffrent and really exciting experiance too.

You have something called priapism, that means that your penis use to be many time in erect position.  Caman maybe it can be a little painful but many women and/or men would be more than happy to can suck it or be penetrated for you for hours and hours!!!!\nThink in the advantages

Males are the only ones that get them.  They occur when a male gets excited and blood flows to the penis. They are also called erections.

Your prostate helps to produce semen, it is sensitive and having it rubbed, massaged, and otherwise manipulated can drive a guy nuts. Or so I've been told.

Is he under pressures lately? Stress can make guys not being able to do so. As for keeping it, are you meaning that he can't stay like this for long or he come too fast? If it's the first one, ask a doctor. Second, get more practices. :P

Switch up positions and I mean often. Time it takes between switching will slow his motor down and maybe even yours but you got to becareful and watch how hard or fast he is pumping you make him go slow from the get go. Find that position that works best for you and not for him. Dont be afraid to go oral or even stroke the guy off while switching up those positions. The is also this toy that you can buy that will wrap around his testicles and penis that will make a man stay harder longer but you gotta keep him hard while your slapping this thing on him. Freaked me out first time I saw it I was like"What you wanna put that on my jewels oh hell nahhhh!" But it was alright...works great when you have had to much to drink and just need alittle help keepin "rocky" in the fight. All in all switch em up is the key to success!

NO NEVER. whanna know why? cause a sexual act can occur only and i mean ONLY if the guy is sexually arroused. that means that he gets stiff. or if a guy doesn't want to get laid, he won't get stiff. \nwhile a woman only provides a ... "hole" to put something in. she doesnt have to get anything hard in order to have sex. therefor, she can be forced to have sex. \nnow, some of you guys might say that you don't have that much control over your little toy, but i bet you never had to say NO to find out if you can controll yourself.

thats a good thing, being tight usually gives the guy more pleasure.  Id go about with my head held high safe in the knowledge that ur friends partner is evidently so inexperiences that he has to cover it up with silly comments

Since the testicles are involved during sex I have a feeling you will regret getting aroused. And that will happen whether you give or get. All you can do is try. If it hurts too bad I'm sure it will go right back down from whence it came. (bad pun) Good luck. Keep some cold water near.

The excitement triggers increased blood flow into the penis, and the swelling blood vessels cause your penis to become erect.\n\nNo one else is giving you a straight answer because they don't know why, and they're pretending to be clever.
