Mapenzi ya jinsia mbili

Mapenzi ya jinsia mbili (pia: mapenzi ya jinsia zote) ni mvuto wa kimapenzi, kingono, au tabia ya kingono kuelekea kwa wanaume na wanawake vilevile. Inaweza pia kufasiriwa kama mvuto kuelekea zaidi ya jinsia moja, kwa watu wa jinsia moja na tofauti, au mvuto kwa watu bila kujali jinsia yao au utambulisho wa kijinsia (pansexuality).

Neno mapenzi ya jinsia mbili hutumika hasa kwa watu wenye mvuto wa mapenzi ya jinsia tofauti na mapenzi ya jinsia moja. Utambulisho wa mtu kama anapenda jinsia zote hauashirii kuwa na mvuto wa kingono sawa kwa jinsia zote mbili; mara nyingi, watu walio na upendeleo wa wazi lakini si wa kipekee kwa jinsia moja kuliko nyingine pia hujitambulisha kama mpenda jinsia zote.

Wanasayansi hawajui hasa nini husababisha mwelekeo wa kijinsia, lakini wanadhani kuwa husababishwa na mchanganyiko mtambuka wa kijenetiki, homoni, na athari ya mazingira, na hawaoni kuwa ni jambo la hiari. Ingawa hakuna nadharia kuhusu chanzo cha mwelekeo wa kijinsia iliyokubaliwa kabisa, wanasayansi hupendelea nadharia zinazoegemea ki-biolojia. Kuna ushahidi mwingi zaidi unaounga mkono sababu za kibiolojia zisizo za kijamii za mwelekeo wa kijinsia kuliko za kijamii, hasa kwa wanaume.

Upenzi huu umeonekana katika jamii mbalimbali za binadamu, na katika ulimwengu wa wanyama, katika kipindi chote cha historia iliyorekodiwa. Neno mapenzi ya jinsia mbili, kama ilivyo kwa maneno mapenzi ya jinsia tofauti na jinsia moja, lilibuniwa katika karne ya 19 na Charles Gilbert Chaddock.
