Will my younger age make sex unpleasurable for her?

Ok, I'm almost 14 years old and my girlfriend is 17. Recently we have been wanting to do more than just make out and kiss. We haven't had a chance to be alone because both of us have been out of town for the past week. However, this Sunday, we are going...

to hang out and go over to my house. We are planning on having sex, and I have a condom and everything, but I'm not too sure how I am going to do. She isn't a virgin, and I am. I'm worried that since I'm so much younger, my pen!s won't be big enough to please her. And I am also concerned as to how long I will last. Is there any way to make yourself last longer in bed? Is there any way you can make your pen!s seem bigger? Please help. Thank you.

Erm excuse me, but your girlfriend...
What is she wanting with a 14 year old?
she sounds liike a pedo to me.
Did you know that its illegal for anyone to have sex when they are under the age of consent (sixteen)
You wont get in trouble... but she will.
Seriously dude, dump her and get a new girl thats more your age.

WAIT A MINUTE! I READ THAT WRONG! youre ALMOST 14
Which means youre ... 13

That is sick dude, downright sick on her part.
Tell her from me shes a pervert and a pedo

Dear confusedkid,
Please call this whole thing off...she should not be your girlfriend at 17. There is something terribly wrong with her. I'm sorry but you are not ready to have this type of relationship and you will be making a fool of yourself. You are not fully developed yet and she will know that. You are going to be embarrassed. Tell her you can't see her anymore. This girl needs counselling and I don't know the laws there but could get in serious trouble for even dating you.
Sue...good luck

yea the laws are diferent all over but you c it all the time people do things and one person ends up in jail because they didnt know the laws I think she would b sick in the head here to bigest age diference for teens is 3 years your beyond that and in most places the age of concent is 16so if you do have sex she could end up in jail and be marked as a pedofile for here its a min of 10 years which meens she wont b aloud to be left alone with anyone under the age of 16 yes the laws suck because that age should b 18 cause thats the age that you can have sex with anyone but thats the way things are

look dude im 14 too I would never go out with some one who was 17 because if u
cared adout her you would not want her trouble.
