As is the case with almost all Wife Sharing husbands, if you already know Hot Wives in a particular community you'll probably be happier if you attend your first few events with these wives. They can introduce you to other Hot Wives. Waiting a little while and watching how other couples behave is also a good idea, as it is in almost any new social situation. It is a key to turn your Hot Wife on as well as in fulfilling your own sexual fantasies.
Common courtesy, of course, is as welcome in the Hot Wife community as it is in any other community; we're all just people, after all. There are several different styles of Wife Sharing which you may see in this community. Some people may prefer not to be around when their wife is having sex with someone else ("closed Wife Swap"), while others may insist on it ("open Wife Swap"). The term "soft swapping" refers to trading Real Wives just for the purposes of heavy petting and then switching back to one's primary partner for any actual sex. It is never required to get your Wife penetrated deep by the other husband.
It might be valuable for you to think about whether there are any potential situations that you feel you would be more or less comfortable in, and discuss these with your Wife. Although not all couples find it necessary to do this, some couples feel more comfortable having social "codes" that only the two of them know. Examples might be discreet phrases or gestures which mean a) one of you is attracted to the people or person he or she is talking to and wants to know if you are interested in swapping with them, b) a reply to the above, either affirmatively or negatively, and c) one of you is not having a good time and wants to get away from things for a while.
At off-premises events such as parties, it's common for Hot Wives to dress up or else wear revealing clothes. Dress at on-premises events tends to be more casual, since Wife Sharing is a common outcome of the evening for many. If there's a dress theme for a particular event, go with the theme. By the way, it is not necessary to actually have sex with other people to have a good time in the Hot Wife community. These activities such as Wife Parties can provide a wonderful opportunity to flirt and be flirted with in a non-threatening yet sexually-charged atmosphere, which can be fun in and of itself. Always try to enjoy all Real Wives present there.
