Obviously shes not understanding .. Just explain it to her . She shiuldnt be so dramatic about it its not all about her its about both of you . Express yourself .

Sounds like a bad case of blue balls. This happened to me a bit when I was younger and getting use to condoms. Whiskey dick is worse.. Moral of the story, shit happens.

She sounds self-centered and insecure.

This would always happen to me the first time with a girl,

Do you not like sex, or you just don't like sex with her? Was this a one time thing or are you just never going to enjoy it with her? Because if you don't enjoy it with her and don't feel you ever will the two of you need to sit down and decide if you care about each other enough to have a relationship that excludes sex. And if the answer is no for either one of you, you need to go your seperate ways.

Well, you aren't denying it...

Your girlfriend needs to get over it. Not all guys cum so quickly and or you could be stressed. Double standards are not fun. Tell you girlfriend to quit being so insecure though it is sweet she wanted you to cum. She should be asking if your ok and if she wants to please you so much maybe she should have gotten on her knees. Good luck talking.

Did she try her mouth? That usually helps.

Just gotta get used to finishing in her instead of your hand... Had the same problem but it gets better.
