Typical Changes in Men and Women as they age...
Female: reduced muscle tension, reduced vaginal lubrication, reduced elasticity of the
vaginal walls, smaller increases in breast size during sexual arousal, reduced intensity of muscle spasms at orgasm.
Male: longer time to erection and orgasm, need for more direct stimulation for erection
and orgasm, less semen, emitted during ejaculation, erections may be less firm, testicles may not elevate as high into the
scrotum, less intense orgasmic contractions, lessened feeling of a need to ejaculate during sex, and longer refractory period.
