Since I like to be on the bottom sometimes and my SO can get my current going. I would have to go with the formula used to calculate inductance on an inverted cone primary. It involves SIN. 
The sine curve. It runs forever in both directions.
I think my head is about to explode. Thanks, all.

If this isn’t evidence that men and women’s sex drives are world’s apart…I mean, I thought “Which cartoon character would you most like to fuck?” was a little odd, but * mathematical functions*?
I’m hanging out with FREAKS!!
P.S. If you MUST know, pi is the only one I’d even consider.
You have a valid point, there. 
I’m not fussy, as long as it’s discrete.
Let me tell you about a date I had. I went out with this function.
I first met her in the bar. I walked up to her and said, “Hey, baby, what’s your sign?” She said, “positive.” After chatting for a bit and going of on a few tangents, it was clear we shared a subset. She gave me her number and asked me to pick her up the next night.
I picked her up at her domain. As she opened the door, I thought to myself, “Damn, she is prime! Talk about a para-bolas!” I gently raised her hand to my lips and kissed her digits. As she walked to the car, I could tell she was well coordinated. Despite that, she slipped on the ice and fell. She was obviously in pain. I asked her if she needed to go to L’Hopital. She declined and off we went.
I had already plotted the course on the map so I wouldn’t get lost in the area. We went to see a projection. It was a double feature. The first flick was the Matrix and the second was something with Elizabeth Taylor-series-expansion. Our relationship wasn’t defined, so I didn’t make any moves in the theater.
Afterwards, we went to a little diner for some pi. We circled around in the parking lot until I found a space. We went inside and ordered pair. After a few times steps, we seemed to be integrating quite nicely. She had some kind of power over me. She asked me if I wanted to go back to her place, so we did.
She wanted to check out our geometry, but she was worried about multiplication. She explained that she had been around a bit—she had some range. I understood, but was a bit wary. She told me I could count on her. We were losing direction with all of the permutations and regressions. I thought a substitution might be in order. I got up and got a couple of drinks. When I returned, I found she had gotten more comfortable. I decided to lie down next to her and started to feel her curves. As thing heated up, we moved into 69 position. The problem was, I could feel an axis!
My mind was in complete dis-array. I couldn’t believe I had derived it sooner. What had once seemed so curvaceous turned out to be completely linear. In the end, I felt like I was living a hyperbola. Take it from me: don’t date a zero.
I’d like to take a round out of a bell curve.
I mean round number! Yeah… 
I’m also turned on by thoughts of unnatural isomorphisms, the domination number of a graph, and (in my kinkier moments) the Stirling numbers S(n,m). 
TMI? 
Sadly not as infinite as you pi would have you believe … that is just something that pi uses to get posters like yourself into bed … beware greek symbols bearing promises of forever.
Nen? Classic. 
As for me, I don’t care which function–just so long as we could do it 6.022 * 10[sup]23[/sup] times.
Nen? You fucking ROCK.
tries to keep from laughing too hard at work
nen, she may have been into you, but you clearly weren’t integer.
You’ll have to write this down to get it.
It’s something I actually saw as bathroom wall graffiti:
The integral of e to the x (skip the dx, or if you can’t bear to, write it really small) = the function of u and n.
Even during the long, drug induced naps that were calculus class, my mind didn’t even come up with anything close to this. But, now that the thought is in my head, the only thing that comes to mind is the quadratic equation.
runs away screaming
I just like watching the mathematical functions calculate together. Now if only my Calculus 2 textbook had a centerfold…
I would fuck a factorial. That exclamation mark has to stand for something. I would consider fucking any function of x cubed.
I don’t know, but my log’s-a-rithmic.
x choose n . . . not only are they stacked, but you get factorials . . .
and Nen, you’re awesome.
now . . . goal for tomorrow: get through two math classes without breaking out in hysterical laughter . . .
I’m also quite fascinated by the combinatorial problems involving forbidden positions…
And it’s when I have sex with them that those perfectly ordinary integers turn into factorials!
