So I'm saying, yes, there were overlapping sexual relationships, that our ancestors probably had several different sexual relationships going on at any given moment in their adult lives.
Ich sage also, ja, es hat überlappende sexuelle Beziehungen gegeben, unsere Vorfahren hatten wahrscheinlich  mehrere laufende sexuelle Beziehungen zu jedem Zeitpunkt  ihres Erwachsenenlebens.
