Coitive

Such men are rarely able to satisfy women, partly because the coitive friction is insufficient and partly because their coitive urges are slight.

Biologically determined coitive heterosexuality was seen as the norm.

We do not aim to eliminate Sex Love, or to suppress its manifestations; but we wish to foster & encourage it; we wish to make real love & true affection take the place of so much depletive, demoralizing, coitive love.

No coitive act should be completed when it requires fatiguing efforts to accomplish it.
