Any anatomy specialists here?

I'm an 18 year old male who can't get hard in bed. Last 4 times it would refuse to stand up. I get hard when we're making out, but when clothes start coming off I can't perform. Is there a specific reason for this which I can treat?

f(x) = x^2 + x + 1
f'(x) = 2x + 1
f''(x) = 2

f''(x) tell us that it is a global minimum and that there is only 1 (Thus a parabola.)

f(x) = x^2 + x + 1
f(-1) = 1
f(-1/2) = 3/4
f(0) = 1

as x increases, y decreases..
It's going down and then up.
Solve x^2 + x + 1 = 0 to find the roots and you're set.

>tfw I almost never get above 60's on tests because professors feel the need to ask purposefully vague questions, then dock marks for me making the wrong assumptions and giving them the wrong right answers or because I'm off by a few hundredths.

I helped my prof properly put together a 3phase transformer in a lab last year because he kept shorting it and flipping the breakers, and then I failed the class because I dun goofed the last step of several questions.

I should just quit and become a goddamn electrician
