Male sex drive decreases. Directly stimulated erections can become infrequent and difficult to maintain. Spontaneous erections usually stop. The testes and prostate atrophy. The penile skin also shrinks if erections are not regularly encouraged.
Breast size increases.
Sometimes the areoles and nipples swell, but generally not significantly, unless the body is less than a decade past puberty. Fat is redistributed. The face becomes more typically female in shape. Fat tends to migrate away from the waist and toward the hips and buttocks. Tactile sensation becomes more intense.
