tumescence

In other words, the process of tumescence is gradual and complex.

In man the process of tumescence and detumescence is simple.

A certain degree of tumescence must already have been attained.

Tumescence must thus be obtained before desire can become acute, and courtship runs pari passu with physiological processes.

It is tumescence which is the really essential part of the process, and we cannot afford, with Moll, to ignore it altogether.

Not only is movement itself a source of tumescence, but even the spectacle of movement tends to produce the same effect.

A state of tumescence is not normally constant, and tumescence must be obtained before detumescence is possible.

It seems best to call the first impulse the process of tumescence; the second the process of detumescence.

In so far, however, as they are aids to tumescence they must be regarded as coming within the range of normal variation.

The æsthetic question, however, remains the same as if we were dealing with tumescence.
