This website will give you more information about a study that is being conducted by researchers at the Center for Sexual Health Promotion at Indiana University in Bloomington, Indiana.

In recent years, there has been a growing movement by manufacturers to develop vibrators that are intended to enhance people’s sexual experiences. However, there has been little research about people’s perceptions about various vibrators and the ways in which people integrate them into their sexual lives. In order to examine these questions, this study will investigate the use of vibrators amongst couples.

Heterosexual couples over the age of 18 are invited to participate in this study. In order to participate, both you and your sexual partner must meet the eligibility criteria and agree to participate in order to be included in this study. An estimated 300 people (150 men and 150 women) are expected to participate in this study.

Couples who decide to participate in this study will be asked to complete a detailed questionnaire about themselves, their sexual attitudes and their sexual behaviors. After completing this initial questionnaire, we will ask you to come to our study website for every day during three two-week long periods (6 weeks) with a one week break between surveys for a total participation period of approximately ten (10) weeks. The daily surveys will include a brief questionnaire about your sexual activities both alone and with your partner along with any products used during sexual activity that day. After you complete the first two-week period of surveys, you will receive two vibrators and you and your sexual partner will be asked to use only one of the two vibrators during both solo (masturbation) and partnered (foreplay, intercourse, etc) sexual activities. After you complete the second two-week period of surveys, you will be asked to use the second of the two vibrators you received during both solo (masturbation) and partnered (foreplay, intercourse, etc) sexual activities. You will receive a total of two different vibrators during your participation in this study ranging in texture, shape, and speed. You will be asked to use the vibrators on the following schedule:

  • Week 1-2: Baseline Data Collection (Complete Daily Surveys)
  • Week 3-4: No Surveys
  • Week 5-6: Use first vibrator (Complete Daily Surveys)
  • Week 7-8: No Surveys
  • Week 9-10: Use Second Vibrator (Complete Daily Surveys); Summary Survey

This study will be completely confidential. We will ask you for an e-mail address so that we can send you information about the study and we will also ask you for your name and mailing address so that we can send you and your partner the vibrators.

All of the vibrators used in this study are currently sold in the United States.

In addition to the free vibrators that you will receive during the study, each member of the couple who completes the study will also receive a gift card.
