As an asexual, I look at sexual intercourse the same way I would look at a glob of unidentifiable mushy paste that was just served for dinner at a fancy party.

I look around and I see everyone else eating it and clearly enjoying it. I know it tastes good to them, I know they like it, because it's very obvious they like it. And I can understand why they like it, because I know that it was specifically made to be something they would enjoy.

But no matter how much you encourage me to try it, no matter how much I know that everyone else thinks it's great, I just can't get past how utterly disgusting it looks to me. I know just from a glance, from the appearance and texture and presentation, that it's exactly the sort of thing that I will never be willing or able to partake in, and I feel absolutely fine passing it up because I wasn't very hungry to begin with and I'd really rather just go home and have a quick snack by myself.
