We like parties as described above By Chocc. Its kind of an all you can eat sex buffet.We tend not to wonder off to different rooms but are ok if it happens. We LOVE when there are limited beds and so each room turns into a little orgy. We attended one a month ago, 8 couples, late 50's to early 60's in an upscale home and we had a blast! 6 of the couples stayed in one room, 2 others were in the other and there was some individual switching off of rooms. In the end, I boinked 2 women, and went down on 3, got my cock sucked by 3 (one to completion). Mrs Doc boinked 5 guys, blew 2 others, got fingered orgasm by one of the women and finally blew the biggest dick in the place till he came on her tits. We left tired, sticky (she was anyway)and very satisfied and had a LOT to talk about the next day by the pool. There is another party in May…we're counting the days.
This was different from one of those parties where someone throws open their house, advertises on SLS and charges admission. Here, we knew several of the couples including the hosts and those we didn't know were known to another of the guest couples. The first time we attended, we were assured that each couple were perfectly safe, had no weird kinks and were comfortable in same room or separate and that they all played well with others. Turned out to be absolutely accurate.
Maybe OP, the group or the group dynamic doesn't fit into your comfort level. Mrs Doc says "If I want a one on one swap, we'll meet a couple from SLS or SDC for drinks and go from there. At a party I like a pile of bodies and a smorgasbord of playmates to choose from." Damn!! I LOVE that woman!!!!
