Hmmm.....I feel that I can answer this with the perspective of the "person who doesn't want sex".
I've done it. I don't like it. I feel nothing, it's boring, I could live forever without it. Does that mean I'm not sexually attracted to people? Of course not. I could see a hot man and think "I want a piece of that o.o"...but in the end....I just do not enjoy sex at all. But kissing, cuddling, etc...that's all nice and whatever, I just don't like sex :/. You're probably thinking she hasn't had good sex, or they weren't doing it right. No, that's not the case at all.
IVIZ- I wouldn't trust my partner (assuming that I had one) to go sex up other girls, ever, no matter the circumstances. I see it as, if he needs sex that damn much...he might as well just go date someone else.
Now finding someone who dislikes sex as much I do. Pft, I might as well be the future 300 cat lady.
