This type of failure happens quite often.It should be take lightly. A simple trick, is to take deep, slow and even breathing. this will dull your sex urge and stop premature election. Google abdominal breathing, learn it and practice it for 10 minutes twice a day. And when you want to control your urge, do slow abdominal breathing.
Your experience is very normal. You are just getting a bit worried about first time sex. Condoms cause many people problems. Stay cool. For the moment just get your girl to make you orgasm with her hand while you finger her vulva.
When a male has pre-matured ejaculation, woman remains hung. It would be a good practice to masturbate your female partner to reach her to orgasm. This could be done by fingering vulva, placing palm on vulva and pressing and releasing , or running fingers around clitoris. Do not touch clitoris harshly. It is very tender , so handle it softly. Masturbating her immidiately after ejaculation, may be uncomfortable for you as you might have lost tempo of sex. Usually it takes half an hour to regain sexual urge.
Yeah it's really normal, especially when it's your first time and you are feeling all awkward. Condoms are usually not sexy at all, trying to fumble around with one of those things is usually awkward and if it's not the right size it can really ruin your erection. The emotional pressure you feel has a lot to do with your sexual performance because you really want to please her.
What you really just need to do is get out of your head, stop worrying, stop thinking, and just start enjoying sex and that might be easier said than done.
I think it might help if you take it even slower. Focus more on the foreplay, get very passionate with her, get extremely turned on so that you aren't focusing on minute details like how awkward you feel. Sex should be so passionate that it doesn't feel like a robotic, akward task.
It might not come naturally when you are still practically a virgin, but eventually you'll figure out what really turns you on.
Even putting on a condom could be amazing, maybe if she does it for you.
