Losing My Virginity

First off, let her know it's your first time and she'll understand unless she's an absolute bitch - in which case you shouldn't be fucking her anyway. Don't fuck people who aren't considerate and nice.
Trim your nails, read a few guides on fingering. Make out with her a long time, do foreplay-ish stuff like kissing her neck and playing with her breasts. Ask her how she likes to be touched. While you're fingering her, take note of how she breathes and responds to certain movements and try to fine tune it for her.

>How can I last longer in bed on my first time
M8, more likely than not you won't be able to cum the first time, especially if you're wearing a condom.

>A) How can I last longer in bed on my first time
Some people advocate jerking off beforehand, but above poster is right that if it's your first time wearing a condom (and if you're not wearing a condom, you may be stupid) your sensitivity will likely be reduced anyhow. Don't worry much. Lots of foreplay for her, don't stick it in too soon (also relevant to the below).
>B) How can I ensure that the girl gets off
Cunnilingus pretty much always works for me. Points above about manual stimulation also make some sense, although I've been with relatively few women who get off with fingers alone. But the best bet is to ask her what she likes and do that.
>C) Any general tips to achieve peak performance
It's your first time. Peak performance is neither expected nor likely. Sex, like most things, takes practice. I recommend you try as hard as you can to relax, talk to her, and have fun.
