If you find any changes to you penis after sex, things that weren't there before you had sex, see your doctor as you might have caught an infection such as an STD. Don't have sex with anyone else until you have seen a doctor because if it is an STD you will just spread it to more people. The pimples you describe might be completely harmless but if they have suddenly apeared after sex it is better to see a doctor and be certain what they are. If they are the result of an infection it won't go away if you just ignore it, it will only spread and get worse so the sooner you seek help the better. It is better to be safe than sorry.
I have not gotten any pimples on my balls. On my penis yes but not on my balls so I am guessing no.
No. Skin problems have nothing to do with sex. Not washing your skin or taking care of it is causes pimples.
If its on the head it may simply be thrush. Try an anti-thrush cream for you and your partner.
Ive had them to, its just that, a pimple. i popped it and it went away in about 4 or 5 days. nothing ever came back
You might have him checked for Chicken Pox.
give them oral sex or pleasure them with your mouth
You should see a doctor.
To give them a blowjob. Aka oral sex. aka sucking their penis with their mouth.
I would suggest waiting until it's a white head, then go for it.
depends have you had unprotected sex, it may be a STD
how old are you? It depends, sometimes a penis is just deformed and it is normal. It wont stop you having sex, does it sting if you touch it? If you are still developing then this is why.
The scientific term for the head of the penis is "glans penis."
