The sexual needs of older people are a very sensitive topic in Hong Kong society. I am thinking of using an online questionnaire for a survey. What do you think? Do you agree it may help?

No worries.

You are right! Thanks a lot!

Thank you for the question. Indeed, the online method avoids embarrassment in a face-to-face survey. However, you may mind about the selection bias issue since all the participants in your study can use the Internet, which excludes those who have no access to the Internet.
