Love and sex are very tangled in the minds of most people. Assuming you are straight, could you really fall in love with someone of the same sex? Want to spend lots of time with them, give them back-rubs when they are stressed, have quiet candle-lit dinners together?

I think people can certainly be friends without sex - but I don't think love works without sex (or at least sexual attraction).

A lot of friendships between men and women have a sexual component - not sex, not even touching - but a low level flirtation.
