I have completed my profile and updated it from time to time. i use the features to 'search' for like minded dudes. What does it mean when a dudes doesn't answer the 'Safer Sex' question. i get Always, usually and Lets' Discuss.... What does no answer mean?
I would not read anything into not answering a question like that. This is not (usually) a dating/sex site, so answering that question might not be relevant to that person. If you find someone you are interested in, just ask them up front.
