not masturbation.....it's probably not acne....could be a rash from a cream or something that you came in contact with or it could be ingrown hairs.....if it doesn't go away in a few days see your doctor

The veins coming out of the penis constrict and keeps more blood in the actual penis than would normally be there.  This causes the penis to become erect.  Also, hormones begin to cause pupils to dilate (believed to allow more image to be taken into the body), the heart begins to beat faster and breathing increases.  I'm sure there's more, but this is all I can remember at the time being.

food can be an issue! greasy foods such as pizza and fries-things like that. it boosts the oil in your skin that builds up and causes acne. alot of things can trigger acne. i know because i had it myself. washing your face to much signals the body that you are running low on oil, so then you get more! you don't want to wash your face more than twice a day! none of my family had acne either. what happens is the oil in your pores builds up and causes a plug. then your skin swells up and becomes red and sore. i would recomend a medication like proactive or acne free! i use proactive and i works like a charm... i used to have bad acne but now you can't see one blemish!

If you're not a virgin it could be syphilis, herpes, or HPV, gonorrhea or chlamydia.  If it looks like a pimple, it most likely is a folliculitis - this is benign, non-infectious, and self resolving.  If you think you could have an STD I recommend seeing a Dr.  All STD's are treatable to some extent, and without treatment some may have dire consequences - also, if you're under 18 (or over), your Dr is not legally permitted to discuss sexual health matters with your parent without your permission.

Some guys have bumps called "pearly penile papules" on their penises, which are normal growths that appear around the base of hair follicles. Also, another fairly common condition is infection of the sebaceous glands, or simply put, pimple-like growths. These infections respond to antibiotics. Both conditions are not unusual, but it is best to be evaluated by a clinician to determine a diagnosis and treatment, if any is necessary.\n\nRemember, some sexually transmitted infections, like herpes and genital warts, can be transmitted through close skin-to-skin contact, even if the person has never had intercourse.

You may have bacterial vaginosis. You can get this from taking antibiotics for acne long enough that it messes up the normal bacterial balance down there. Go have yourself checked out by a gynecologist. They can prescribe something for you to clear it right up.

yes around, not right on the private. Pimples occur where ever there is more sebacoues secretion that remains unattended or is too much.\n\nFace - too much\nBack - unattended\nAxilla, groin - too much, due to hair cannot be well attended.\n\n\nSkinny girls are worst when you have pimples in the groin - they pimples really hurt to much since the skinny girls bones hit them!

Simply that baldness is a sign of virility and acne is a sign of worry.  There may be other assumed conditions that apply, but I see that your looking for the simple answer.

acne is pimples or irritated and clogged pores. It happens to teens most because of puberty and the horomone changes that occur during it.

It could be from shaving.  If you shave to close to the skin that could happen.  Or if you don't use a mosturizer after shaving that could happen.  Just try some mild mosturizer.  \nI hope it helps!!

He just needs to wash his face.  If you shave down there it could be the irritation from rubbing his face against you or any soaps, perfumes, powders you might have used that day or right before that he could be slightly sensitive to.  I highly doubt it is an STD.  If it blisters and shows a more red appearance then you might want to see the doctor, but for now use an good facial cleanser...just treat it similiar to acne and it should go away.  Good luck!

You are probably thinking of a staph infection.  Staph is a bacterium that can be found everywhere and, when it infiltrates a human system, very dangerous.  I don't know from your question exactly what form the staph infection is taking or whether or not you've sought treatment, but I'd advise you seek a physician's help.  Bumps on the face and genitals caused by staph could be serious.
