Welcome to the lifestyle bro! I'm 47 and been been in the lifestyle for at least 13 years. Been to lots of private lifestyle parties over the years.
Be presentable and dress casually smooth looking good and smelling good. Make sure you are well groomed from the hair cut to trimmed man areas. As long as you are visually appealing and attractive that is definitely a huge door opener and cuts your work of getting to know some women in half. Meaning if you are hot looking and hung they're fuckin! Trust me alot can by bypass a potential playmate who's a knucklehead or has an attitude as long as they got the goods, but nothing works better than good old fashion charm and being a well spoken smooth gentleman!
The best thing about parties is the potential for making connections and networking! If you fuck one woman in a room full of people and you drive her crazy and get her off good in front of everyone then every woman in that room is gonna want that same good dick! Most of them will definitely want a turn and some will even get your info so they can hook up with you in private. Most of the parties I have attended I probably banged every woman at the party every time.
Keep in mind people who throw private lifestyle parties tend to fill their guest list with people who are as attractive as they are. At least that has always been my experience here in Southern California.
Always be friendly and smiling and a gentleman. Always ask first especially if you are not sure! For example: you are at a party and you have already played with a few women and you see a woman and she is playing with 3 other guys and she absolutely looks like she is enjoying all the attention. Her hubby is right next to the bed watching and taking pictures. You want to join and give her a 4th cock to play with but you are not sure if it's cool or not? Get hubby's attention and say "may I join"? Nine times out of ten they will be generous and say yes! Most probably wouldn't even object if you joined without asking but as a veteran bull in the game and a gentleman I advise you to always ask!
Also if you like a hotwife that you see and you want to play with her at a later time then ask her for her contacts info. Out of respect if she is clearly married or has a boyfriend always refer to them both and never make her man feel like you are trying to cut him out of the picture. Basically say "hey I would love to hook up with you guys in a more private setting for fun how can I contact you and chat with you"?
As far as performance goes always come with your A game bro! If you come with a limp dick trust me they will be nice but sorely disappointed and every other bull or young stud they meet will hear about is as one of their most disappointing experiences! They love the excitement and the young energy and stamina of young guys. Quick recovery but young guys don't tend to focus enough on making sure everything that they are doing is pleasurable to the woman. Don't just be energetically pounding away trying to get your nut off! Actually make sure you are making her cum as well and you will get that repeat invite.
Ok hope this advice helps. If you have any questions just message me. I always willing to put someone up on game! Have fun!
