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.
You may be confused. Girls do not have a penis.
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.
It is wrong to say "the penis grows when a girl is around". Actually, the vessels inside the penis relax to let more blood into the veins of the penis (we call it cavernous vessels). This engorgement of vessels makes the penis get larger in case the girl is available for a penetration. This is called erection, not growing.
If you have a big penis and want to marry a girl it is a bonus because your girl could suck off it for ages and still want more but if you have a samell penis you can still marry a girl but not have as much fun as the dudes with big penises do. :)
