As to the original question here, wouldn't make a difference to us if someone said they normally didn't use condoms. But then again, we are one of those couples that will freely admit that we prefer not to use condoms.
Based on some of the responses though, I do have some observations we have made that may be something to think about.
First of all, we have noticed that on average, the people we have seen doing things that are known to be the riskiest behavior for contracting std's, were usually "condoms only" couples. For us we would gauge people more on what risks they are willing to take over whether they use condoms or not.
Second, we have noticed that most swingers, when asked, will say they are condom only, whether they really are or not. They do this for the very reason that this original question was asked. And that is, because it is well known in the swinger community that some "condom only" folks will not consider playing with them if they find out they prefer not to use condoms.
Lastly, we know several "condom only" couples that will basically do anybody. It isn't unusual for them to have sex with 3 or 4 different people on a average night at the club, and they usually go to the club a half dozen nights a month. Others are more like us, we are very selective when choosing people to play with. Therefore, even though we may go to the club as often as the previously described couples, we probably only have about 6 or 8 different sex partners in a year. If you are even vaguely familiar with the risks of std transmission, it is obvious that you are at much less risk with the latter type of couple than you are with the former. Even though, the former is "condoms only" and the later is condoms optional.
I think the thing that bothers me the most personally about the condom issue is the level of false sense of security most "condoms only" folks attribute to their use. The fact is, they provide little to no protection for the most common std's. Yet many folks actually believe that once they slip that condom on they are safe. When you mention this to folks who are condom only, they will usually say something like, "oh, I realize they are not 100% protection". But in their mind they actually believe that they are 70% or 80% or even 90% protected when using condoms, when in reality, condoms might provide, if you put the most optimistic slant possible on the available data, less than 10% protection for the most common std's over no condom at all. It is this false sense of security people have regarding condoms, that I believe often leads people to engage in risky sexual practices without a worry, that they would never consider without condoms.That is what scares me away from those people more than anything.
