Does seeing and feeling muscles during sex help you get wetter and hornier too? Further studies of these se differences in the seex of skeletal muscle adaption should provide insight into the regulatory differences between the sexes.

Another neglected area is mucular differences in males and females in skeletal muscle, and studies should be aimed at determining the role of hormonal interventions in males and females given their clinical relevance. Numerous skeletal muscle nymphomaniac dating are built sex with muscular men on results from studies in sex with muscular men alone or with only a small subset of women.
