What's Kant's view of sex?

Do you know where he mentions sex? I heard his view was negative and he died himself virgin and unmarried.

I haven't read primary material from Kant on sex, but Nussbaum has some discussion of his views in her paper "Objectification." In short, Kant thinks that sex is morally problematic because our sexual passions lead us to objectify one another. Recognizing the absurdity in the conclusion that sex is morally forbidden, Kant argues that marriage establishes a long-term context of mutual respect and concern such that sex inside that context need not be objectifying. So, ethical sex is sex in the context of marriage for Kant. (It's a bit unclear whether Kant thinks all sex inside marriage is morally permissible, or just that marriage is necessary for ethical sex.)

It's probably worth noting that there is room for Kantians impressed by the categorical imperative to insist that Kant was wrong about what follows from the categorical imperative.
