Almost 17, penis is barely 4 inches erect?!

Let me start off by telling you that I'm a girl :) quite frankly your sexual relationships shouldn't be affected by this, and if they are then the girls you are getting are shallow. Get to know the girl first, be comfortable talking about sexual things, and you can perhaps mention that your penis size is below average, let her see that you are slightly uncomfortable with it. Most women will be very understanding, especially if they are more mature.Try not to let it bother you, everybody is different and everybody wants what they haven't got, believe me girls with curly hair want straight hair and vice versa, a guy with an above average penis can easily hurt a girl when having intercourse so he must be especially cautious, at times he will wish it was smaller. You should be proud of your body, it makes up who you are and nobody half decent is going to say anything to you about it. Be prepared for lots of talking when having sex however as your partner may feel that a different position would allow you to more deeply penetrate her etc.don't take offence to this, use it as a learning curve. If it does prove to be a problem, talk to your GP about it, don't be shy or embarrassed they see far more every day, perhaps they could discuss increasing your testosterone levels or equivalent.

Well, it might be a little embarrassing, but it shouldn't impact sexual relationships. In theory, a 3 cm dick is all that is needed to get the job done for the girl. It is small, but give it a year. If not, ask a doctor. And I know asking a doctor sounds ridiculous.

your still have until 21 on average and in some cases 24-26 to finish puberty dont worry oh and i kno you've probably heard this but its how you use it so as long as you know how to give good head and or work the clitoris just right youll be fine

Just be happy with what you got, I'm 20 and Ive got a 5" penis, I'm happy with mine. You still got a couple of years for yours to grow!! Also if you seach micro penis. You will appreciate your size more

You might not grow at all or you might just grow in the next couple of years, no one knows, but I doubt you will and the size you are at is really small dude.

Bro go see a doctor or get some "get bigger pills" that's not good man but don't worry slot of people are small I'm small I'm only 6.5" erect so it's ok but u need to see a doc about that

You are probably a late bloomer, see when your friends got facial and armpit hair and if you got it around the same time then go see your doctor he can give you growth hormones

Ouch. Good luck with that one stubby.

LMAO...Good luck pal
