try sls..swingers life style or fetlife....you can pick what you want yet you will have to be a member of either one...

I am a member to a private club that might be of interest to you. They're a very nice establishment and offer an array of themed nights that might fit your needs. Not sure how they feel about a plug on here, so I'll refrain but feel free to reach out to me personally.  

I have a membership and often attend parties with clients who request attendance with me. It's not something I advertise since I need to be selective with this process and may offer it as a public VIP service in the future, but I do enjoy introducing clients by bringing them as my personal guest. Some enjoy receiving a sensual massage while being watched or like playing in the different themed rooms. Has always been a real erotic experience!  

Good luck with finding a party for you and your girl! Sounds like you two are quite a fun pair! I also give couples massages as well if you both would like that  See my website under the page "Couples Massage"
