Yes and no. That is something that often takes place but many people go to such places in order to be in a place with like-minded sex-positive people. And even if they are actively seeking sex with someone new, the level of entitlement to female bodies is remarkably noticeably much less than in the regular world. Women in such places wear very scanty clothing, but nobody assumes that she is "asking for it" or thinks they can stare, comment upon, grope or otherwise behave disrespectfully. Consent is taken very seriously and in most places anyone who violates that gets ejected from the club because they are messing things up for others by behaving that way.

Just like vanilla people, swingers aren't looking to get with just anyone - they care about chemistry, mutual attraction, and some level of compatibility even if it's mostly just sexual. So, even if you are hoping to get with someone new, it's possible that you might not meet anyone interesting that night and might instead just hang out with other couples who are your friends. Men in these venues (where there is alcohol and nudity) behave like mature adults which indicates that other men could as well if we had a larger culture that demanded it.
