Particularly the thickness of the sex organ

I see that stimulating work with people. Talking interacting actually helps one grow taller, better voice, higher IQ. If you are less than 18, keep reading, exercising, learning. It may do more for you than you think. Even things like beard growth, deepness/richness of the voice, intellect.

I think the male anatomy is beautiful. It's contrast to the female anatomy should be appreciated! And the way both come together perfectly is magic. Maybe you should date a real woman instead of the girls you have obviously been dating.

Sorry, I think there is nothing to do. Any penis gets its own structure and only some surgical operation could change its shape. But doctors do it only if there is some serious obstacle for the sexual act (penetration). On the other hand, the most part of the penis curves up.... so it shouldn’t be an important matter, at least!

Depending on the location and look of the bumps it could be many things.  Link provided has a nice little article about different bumps on a penis.

Girth...Length is good...but in the end your cervix is usually like 7-9 inches back. You feel girth against your walls, and of course 3 inches and thick isn't going to do it. A balance of both wouldn't be too bad though...

Yes, when you diet and exercise properly, all the fat in you body turns in to sex muscle. It collects in you penis and will make your penis longer and thicker. The more you exercise the bigger it gets. Oops... my nose just grew an inch... call me Pinocchio!\n\nTerry

we are more similar than most realize, esp if we look at the embryological origins of these m-f tissues.\n\nInternally both genders started out with NON-differentiated gonads.  If the XX is present, this turns into an ovary in embryo USUALLY.  If XY is present, then it turns into testes USUALLY.  \n\nIn the embryo there are also BOTH sets of tubes: Wollfian ducts and Mullerian ducts.  Wollfian ducts will become vas deferens.  The Mullerian duct will become the oviduct-Fallopian tubes. Pseudohermaphrodites might not differentiate thoroughly.\n\nExternally we all started out as an anatomical female.  Essentially a guy is a closed up female.  During embryo-fetal development the genitals of the baby are very confusing if you don't know what you are looking at.  Essentially, the penis that grows is an enlarged clitoris.  It has 3 erectile tissues in it, where as the clitoris has 2 erectile tissues.  (clitoris does not have the urethra growing in it, so she does not urinate with a clitoris) Many people call the clitoris a small penis, but embryologically speaking it is the other way around.  Both genders have labia in utero....the labia stay and persist in the female, but if it is an XY, the labia are supposed to close up.  The seam seen on the underside of the scrotum (separating the scrotum into rt-lt halves-compartments to hold each testicle) and the underside of the penis (kinda looks like a scar, but it is NOT a circumcision scar, it is the seam where he closed up when his genitals were more female. \n\nOne of the most common birth defects found in the penis is hypospadius, where the underside of the penis has not closed up all the way and so the urine comes out the underside of the head of the penis instead of the tip of the penis where the normal urethral opening is, thus the penis is not completely masculinized and closed up. There is a rarer deformity called epispadius, but the urine hole is on the top of the head of the penis.\n\nThere are both true hermaphrodites and at least three kinds of pseudohermaphrodites in humans.  True hermaphrodites have both ovary and testis.  Pseudo have either or, but the other organs are all mix-match male and female combinations internally and externally.\n\nDuring embryo development there are critical hormonal changes that help to masculinize the brain of males.  If baby is an XX then the masculinizing hormones are not released and the baby's brain stays feminized.  Mothers who take masculinizing hormones during pregnancy can masculinize their daughter's brains.  They might also turn a normal genetic female into a anatomical male.  (Happins in animals too, can get a whole litter to be males if masc hormones given at critical time of embryo dev.)  \n\nAlso females transexuals who take testosterone as adults will go thru a male puberty and be very transformed a lot within 6 months.  They will grow a lot more hair (beards, body, etc) they will grow a bigger larynx, muscles will get leaner-muscular, voice will deepen, their clitoris will grow to be about the size of a thumb and their sexual aggression with be peaked.  Their family will not recognize them in 6 months.  \n\nThus, males and females are a lot a like.  It is easy to make a male to female transexual surgically because you are taking away the male structures that were ADDED at embryo development.  When you make a male from a female transexual, stuff has to be ADDED to make the female.\n\nThus everyone starts out with the feminized brain, feminized genitalia, and BOTH sets of m-f tubes internally. We have structural homologies of all our organs (in the opposite sex) If all goes well, however, the genetic sex and the internal-external m-f traits all match, PLUS the sexual-gender identity will match the chromosomes and the genitals-gametes-gonads.

Have you heard the saying,"a bad workman always blames his tools!". Same thing here. Size don't matter, its what you do with it that counts and that is speaking from experience. I was with a guy who was 9 1/2 inches and it was also very thick but he didn't av a clue how to satisfy a woman. He thought because he was big he didnt have to bother with foreplay or finding out how to turn someone on. Useless! Take the time to perfect your skills and see what turns her on then the only moans you will hear will be pleasurable ones!

The following are the characteristics:-\n1.Physical dimensions of all related organs of the body\n2.Whether required biological changes will be as required.\n3.Whether certain activities connected with sex will be considered dirty.\n4.Whether the other party is willing to co-operate honestly.

It's about the width of the of the body part and the depth and all that other stuff.

Hmm. Really? I don't know what kind of doctors you're going to...\n\nWell, the first obvious thing would be that the Hymen is broken. Boom. Right there, Doctors wrong.\n\nThe second thing is, if the intercourse had been within the past couple days, possible cuts, semen or sperm, and generally, ravishing of the labia and the vaginal tube.\n\nThe vagina will also be wider.
