Is this normal during sex?

[Michael L]

Hi my name is michael, i am 17. I am 6 foot 2, 170 pounds, and my penis is 7.4 inches long and 3.2 inches wide. I met this girl a year ago and we have been going out since then. Not to long ago we both decided to have sexual intercourse and she told me she was a virgin. The first time we had sex she yelled allot! But i've been told it hurts the first time a girl has sex. We've had sex about 15 times and she keeps screaming. One time we had to stop having sex because she was going to wake up her parents. Please tell me, is this normal. Sometimes it looks like it hurts her and that makes me sad because i love her and i don't want to hurt her like this. Please i need answers!

it is normal.
your penis must be too big for her vagina.
just like mens penis vary in size, girls vaginas do too.
