There is no imbalance in sexual intercourse with the wifesharer and his partner, although some wifesharers tend to be dominant. Sexual activity usually takes place together.

During sexual intercourse, the wifesharer forms a threesome with a man and the female partner, in some cases the wifesharer watches and enjoys the erotic situation with or without masturbation.

In some partnerships, the wifesharer determines the woman's sexual partner. In rare cases, the wifesharer also accepts meetings between his partner and another man without himself. Wifesharers usually do not feel jealous.

The man called in is either a household friend with whom the couple has regular or occasional meetings, or they are changing acquaintances with whom the couple has only one or a few contacts.
