The person in the swing can't do a whole lot. The person on the floor can move the swing up and down and back and forth if it's on a spring, which is fun.
I have found that some guys who aren't entirely comfortable being in charge don't enjoy the swing (when I'm in it), for the reason I already mentioned, when I'm in the swing I can't do a whole lot to participate so the guy has to be comfortable being in control.Anybody have experience with them? Fun? Over-rated? Any local ladies have one? Just curious if they're actually something worth trying or more hoopla.
Ok, so this is just my personal opinion. I was obsessed with them for a wile because I REALLY wanted to try it. I ended up trying one at an adult club and it wasn't "all that" Its worth something to try but don't overly expect anything. XOXO, SK
There is a lot of different swings and price points. The comfort of some of them is simply not there. Some are certainly more comfortable than others. Access and positioning also varies from one to another. The bar up top can be an issue as well. They can be a lot of fun with the right swing and right people allowing for positions not possible without it.

If you want to fuck for a long, long time, without wearing out your knees, etc., a sling is truly an amazing thing to have around. Sometimes I play with men who want me to bone them for hours and hours. It's so much easier and more fun with the swing. Plus, as a top, you have total control over the body of the person you're penetrating in terms of rhythm, etc. The swing allows you to move the other person on and off your dick instead of (or in addition to) having to use your hips to do the thrusting. It can take some time to get used to the motion, but once you've got the "swing" of things it's a really wonderful addition. You have to get a good quality swing, of course. As many have mentioned, not all are created equal, and many of them are uncomfortable.
I don't have one in my Incall in NYC currently, but I'm wanting to get one... because I love them!!

I have one hanging in my bedroom and all the asian girls know what it is!

its also very comfortable for sitting in and watching tv.
When my back went out it was the only place I could sit
or your naked ass will be on the floor
with lifting your partner up while standing? Is the experience similar or better?
I love mine! It fits over the door, so any sturdy door jamb can hold it.
I think it's worth trying, especially if you're adventurous with positions 
It's a bit tough to get in and out of though...

Thanks all for the feedback. Sounds like something worth a try if it's there, but probably not worth making an extra effort unless I've discovered a personal affinity.
