Yeah, that Hacienda place does look like a swinger or kink club, with an "atmosphere of beauty." Even though they say they accept people of all ages and body types, obviously that's a lie. The group photo there is full of people who all seem to be under 40, and everyone is draped all over each other, wearing sexy fetish gear, like they're about to engage in a big orgy. That's not polyamory to me.
I've been actively poly since 2009 here in Massachusetts and I've only engaged with people in perfectly (contemporary) traditional dating ways, chat online, meet for dinner, maybe sex on the second or third date if there's a click. I've had a few threesomes and one foursome, but only with people I knew quite well and trusted. My one-on-one sex experiences far far outnumber my group sex experiences.
I've never belonged to an irl poly community, although most of my friends are queer and poly just because we share those qualities. I've made my friends one by one, not by joining a big readymade group.
I can see why a place like Hacienda would end up with sexual abuse in its ranks. It's the perfect place for predators to go for victims.
I once dated a guy who had been into the "kink lifestyle" when he was younger. After we'd been dating a while, I agreed to go to an actual kink club with him in Providence RI. While they were happy to take our money at the door, I found that only the younger people were playing, flogging, fucking, and the older people were standing around fully clothed, talking, and just watching the young people out of the corners of their eyes. My partner and I went to a semi private room to have a little fun. No one offered to join us. A couple people watched and cheered us on a bit. As we left, the owners asked if we had fun, and after we unenthusiastically said yes, they told us it was an "off night." Hmm...
Polyamory isn't a "lifestyle," (we don't need or want code words like swingers and kinksters seem to) and it doesn't imply group sex, or going to clubs to "discover your sexuality" (as Hacienda's page says). You can be asexual and polyamorous.
The fact that you said you and your husband, "we," had a profile, implies that you're thinking with a swinger mindset. You might be unicorn hunters, expecting to find a hot bi babe to share. I'd recommend dating independently. Of course, women will get hit on more often, but it's just as hard for women to find a proper partner as it is for guys (because most guys that hit on poly women are just looking for an quick hookup). Men need to write really good profiles, have several well-shot pictures of themselves, and be caring, interesting, good listeners, and charming when they first start chatting back and forth.
