Notes"「朝セックス」が気持ちいい理由については、脳内にある「ノルアドレナリン」という物質が関係している。脳内ホルモンの1つであるノルアドレナリンが分泌されると、性的な興奮が高まり、脳内の快楽物質の分泌が促進される。このノルアドレナリンの分泌量は朝起きてから3時間程度が一番多く、その後は徐々に分泌量が減っていく。したがって、朝起きてから3時間がセックスにベストな時間帯なのだ。特に女性の場合、「朝セックス」をすると女性ホルモンが活発に分泌され、1日中肌が潤い、髪も輝くとされている。"性医学の専門家が推奨！ 「朝セックス」のススメ - メンズサイゾー (via opwq) (via talkabout) (via fukumatsu) (via ipodstyle) (via yaruo) (via motomocomo) (via angrypassion) (via kml) (via vmconverter) (via pinto) (via konishiroku)
