You'll need some O-rings to attach a dildo to your harness. The harness comes with one, but it might not fit the dildos you want to use it with. I have a variety of harness-compatible silicone dildos, so I got a cheap pack of various sizes that fit my needs just fine. Any of my silicone dildos with flared bases worked great with these rings and the harness, though the 1.5 inch ring on the 1.5 inch diameter dildo was a tight fit when you have to fit the leather snaps through there as well. I did notice some black smudges rubbing off onto my dildo after putting the ring and leather snaps on, and I'm not really sure which part was rubbing off, but keep in mind that you might want to wash or wipe down the dildo after you've gotten it into the harness. It takes a little time to situate everything properly, so don't expect to be swapping dildos in and out all night unless you practice a bit with your harness first. Pick your favorite and run with it.

The harness is highly adjustable with all of its leather straps. It sits low on my hips and it will not stay put if you try to angle the straps higher and up closer to your waist. The straps at the back are meant to go underneath each butt cheek, but you can adjust them to sit together in the middle if you want to. My dildo did not point straight up like you might expect but hung down a bit. It's hard to defy gravity with a sizable silicone dildo! I'm sure it would be fine for sex.

You do want to be careful with keeping your leather clean because you can only wipe it down and it is porous. So, you'll probably want your own harness rather than sharing it between multiple people who will take turns wearing it, unless you're fluid bonded. I would be especially careful with straps that sit near your ass. Fortunately, I could get quite a bit of pleasure from this harness by wearing it over underwear, and then I don't have to worry about keeping it clean so much.

As for actually using it to strap on a dildo and fuck someone with it, I am afraid that I was unable to do that. It was my first harness, and I thought I might be able to use it with someone, but that turned out not to be the case. However, from my experience just wearing it around for a couple evenings, I would say that I had great control over the dildos I strapped on and I would be totally comfortable using it with a partner. Of course, the bigger the dildo you attach, the more flopping around you're going to get and the more careful you will have to be. Beginners might want to start with something small so they don't hurt anybody (or accidentally knock glasses of red wine off of side tables and onto the floor!).

I'll admit, I bought this harness more for fun than to use during sex. I have always wanted a leather harness for a strap-on, and I used Halloween as an excuse to add one to my collection. I went as an "inappropriate sex-ed lecture." I'll leave the details to your imagination, but it involved sticking the biggest dildo I own (Tantus Silk Large) in the harness, which I wore over fishnets and a pair of panties, with a short dress on top. While any cheap harness might have been fine for my purposes, I don't like to buy cheap, disposable things when I have the choice. I wanted a harness that I could use sexually later on, if I find a partner with such an interest, even though I was not fortunate enough to try it out with a partner. It might sit in my toy box for awhile, but I plan to take good care of it and update the community if I have another opportunity to test it out.

The harness was everything I imagined and more. I was comfortable in it all evening, and it was easy to take off and put back on when using the bathroom. If anything, I was more than comfortable, because the base of the dildo pressed directly on my clit whenever I bonked anything with the giant dildo I wasn't used to having attached to my crotch. Serving yourself some punch at a kitchen counter? Washing your hands after using the bathroom? Walking down the hall while watching the giant dildo bounce around? Instant and unexpected clit massage. I could definitely see how someone might get off by using this for a sexual act, either by a blowjob or fucking. I, for one, was unintentionally aroused all night, a welcome surprise I was not expecting when I bought it.
