<human>: Ok Reddit help me out, this is embarrassing but I will ask anyway.  I am 25 and in a sorta new relationship. Everything is great with the exception of one problem. With this girlfriend my sexual stamina has plummeted. I'm talking 3 minutes of fun and done, I haven't had this little control since I was 16, American Pie style premature ejaculation. She doesn't seem to mind and does the whole "aww thats so cute" (which makes me feel oh so manly) Furthermore, even the second and third time we get it on I have the same issues. This is upsetting because this was my previous Ace when all else failed. To make matters worse, *right* before we started dating I went through a string of emotionless hookups where *I* had problems finishing. 

So help me reddit. I am at wits end. Like I said, when I first started sex yeah this happened. But that changed with experience and I got pretty fucking good (no proof, but you'll just have to believe me.) Sure I wasn't always on my A game but I have never been this consistently bad with any girl ever. 

So is it medical? Am I just psyching myself down?  Any and all advice would be appreciated.  Maybe share stories of commiseration or maybe give me some super secret awesome reddit sex tips (that help me last longer than 2 minutes.) If you give tips please stay away from anything learned in your first 5+ years of sex because **none of those** work for me anymore. 

I doubt anybody will see this, but I would appreciate any responses you guys can give.
Also please pardon my puns, they were unavoidable.

Can you summarize the given text in a few sentences?
<bot>: I used to be pretty tight in bed. Now with my new girlfriend I cant make it past 5 minutes. Need your stories and tips
