Oh boy

your virginity is not your entire sex life. whatever happens tomorrow is not what sex is going to be like for the rest of your life.

it will likely be awkward, sloppy, a little weird, a little anti climactic, but still insanely fun its own way. you will have millions of different kinds of sex, ranging from beautifully passionate to quickies just to get it out of your system, to regret sex, to randomly hot sluts gracing you with their vagina, to this and that and the third thing.

so just go in tomorrow wanting to have fun.

Use protection

Pretty much this.

Dont't try to perform. Just take it slow, and enjoy it.
Be mentally prepared for failure (finishing early, most likely) and plan in advance what to do if it happens.

Don't hold breath

There is no way for you to be able to predict exactly how things are going to go down, and even if you try to, things never go the way you want.

Calm down, don't make it into a big deal, and enjoy yourself. No matter how good or shitty it is, it'll be a memory you have for the rest of your life you'll look back on fondly.

But getting nervous or too critical of yourself will do more harm than good.

You're evolutionary equipped to handle the basics, so focus on that. Impressing her takes skill and practice, so don't worry about that on your maiden voyage.
Insert penis, do what comes naturally, relax and enjoy whatever happens.

PS: There was a clock on the nightstand during my first time, and I lasted 2 minutes. Second time i gave her a vaginal orgasm still without knowing what the fuck i was doing.
