A German study published in October 2021 wanted to know what factors are associated with an orgasm or multiple orgasms in women. Could they be due to certain practices, masturbation, or other factors?
In women in a stable relationship, they asked about the type of sex they have, if they masturbate, if they were satisfied with the sex they have, if they are in love, if they are intimate with their partners, etc.
The results showed that it is the women who experience the most feelings of love or intimacy with their partner who experience the most orgasms, and of course, multiple orgasms occur for those women with more active sexual lives (both in diversity of sexual practices and frequency).
