The survey by Durex, the condom manufacturer, and YourTango.com, a relationship website, also found 92 percent of the website readers said it's a turn-on when their partner shows some vulnerability, because it is an important part of emotional closeness.
Respondents ranked "being with someone I love" as the top confidence booster in bed, followed by "feeling good about my sexual abilities," and "when my partner compliments me," the survey said.
Nevertheless, respondents indicated great sex cannot exist without the three elements: physical attraction, emotional intimacy and feeling secure/loved.
"We've been conditioned by the media to believe that sex is primarily physical and a couple's sex life will inevitably fizzle with time. However, these findings indicate just the opposite -- getting closer on an emotional level is the key to getting closer physically," Andrea Miller, YourTango chief executive officers, said in a statement. "Still, the majority of respondents reported having sex one to two times per week but would like to have sex three or more times per week."
Ninety percent of respondents indicated it was possible for sex to actually get better over time.
