15 year olds shouldn't be having sex.
Only if you want to stick it in her back door
First if it is that small you should get it looked at by a doctor and second you could satisfy a girl who had a small enough vagina. Always wear a condom and always make sure you are of age.
It is a little below average for an adult male on a worldwide ave but it is certainly enough to work with and satisfy a girl.
First of all;trys=triespenus=penisAnd the way you have worded your question makes it seem like you are asking if the guy can stick his penis into the girl's "penis". Please re-word this so it remotely makes some sense.
You rub her first on her boobs the you pull down her pants and rub your penis every where around there and maybe have some sex.
No - if a girl has a penis then she is physically male and thus doesn't have a uterus, as such she does not menstruate.
depends on how intense the relationship is. holding hands is first level, Making out is second, and you should be able to gues the rest
You may be confused. Girls do not have a penis.
It depends on what term of satisfaction you are talking about...
Most likely he'll allow it, but ask your mother first.
The size of the penis has nothing to do with your ability to get someone pregnant. Its your sperm. So yes you can get a girl pregnant with a 4.5 in penis.
Length is less important then breadth given that in most women the penis can only be inserted so far. Between 3 and 5.5 inches is normal. Although cliche it's not that size that matters. But how you use it. The larger it is the more chance of you causing immense pain.
