I'll get to the point - I've had four (large) children, though our sex life is still pretty fantastic and I have no issues reaching orgasm, I had hopes that these would give it just a little boost. I'm glad I tried.

Are they simple to use? Yes. I added a few drops of the enclosed lube and popped them in. ( I definitely suggest using the lube) That's it. I walked around with them for a few hours and took them out before bed.

I can't say I noticed that they were there all the time that I was wearing them, but when I did notice them, they reminded me to do a few kegels ( much more fun with the balls in place!)

After a few days of wearing these (for a few hours a day) I noticed a definite difference in friction the next time we had intercourse. (So did he!)

They are quiet and discreet - they make no noise - no one knows that you're wearing them, and they are simple, fast to insert and remove ( all bonuses for me!)

The duo may be a bit much for smaller framed women, or those who haven't had children. In that case, you may want to opt for the uno. I'd also suggest working up to all day wear - perhaps an hour the first day, add half an hour a day for a week until you work up to having them in all day. Walking seemed to intensify the effect and I always took them out and cleaned them before bed ( usually with just some hot water and soap, though toy cleaner would be another option.)

I do wish that they came with some kind of storage bag/case. I don't feel comfortable throwing them in a drawer ( hello, they're internal toys?), but keeping the packaging for storage is a pain. I'm still looking for something appropriate to store them in overnight or when I'm not wearing them.

Tips: Absolutely use lube and work up to longer stretches. I'd say use them for an hour or so the first day and work up to all day wear for best results!
