I have never really had a problem with premature ejaculation, but I have the past 3 or 4 times i have had sex with my new girlfriend. She is extremely passionate and sex can/has happened in a few random places... Each time in these specific cases, I have lasted less than a minute. Once, the very first time we had sex actually, we went to a hotel and i didnt have a problem at all. Since then, I have been a mess with it... What can i do to fix the issue?
