At 13 you begin going through puberty. When this happens your testes begin producing testosterone for the first time, some of this testosterone is naturally converted to estrogen, which causes sensitivity and growth of breast tissue. The overgrowth of breast tissue in men is known as Gynecomastia
The same thing is happening to girls when they go through puberty, but they have much more estrogen and actually end up growing breasts instead of just a little swelling/discomfort.
No, this is fairly normal for boys in puberty.
Boys breast tissue swells during puberty. It is temporary.
3 weeks with mum (then boys need to go in separate cage) u can keep all boys in same cage providing its large enough, to sex the hamsters easiest way is to sex them at exactly 1 week old, and again at 2 weeks old (paying attention to the nipples on their bellies (girls) those that don't have two long rows of nipples on their tummies are boys! It's easiest to sex them at exactly 14 days old (any later and fur starts growing and covering the nipples, any earlier and they aren't as visible yet! ) as for sexing at 1 week old u can see faint rows of raised "dots" which will later develop into those nipples, if u take photos of the babies and note which are GIRLS, at 2 weeks old, then when they are 3 weeks old all u need to do is refer to the photos and just separate!
You can't decrease the size of your nipples. During puberty all boys nipples get larger but some boys also experience temporary enlargement of the surrounding tissue. If this began when you were 12 and you are now 14 it will probably begin to go away pretty soon.
All healthy humans are born with nipples.
No. Every person normally has nipples.
what kind of question is this sick ass
Old nipples are dark brown and rather wrinkly whereas young nipples are pink or very light brown, plump and wrinkle-free!
NOBODY WANTS 13 YEAR OLD NO DICK BOYS ! come back in 2 years .
Yes they do my two girls are both 23weeks and they have nipples :)
They havent gone through puberty yet.
Yes. Nipples grow larger when women start puberty... If a 10 year old girl hasn't started puberty, her nipples will be small
