So I have to be honest I am sooo not a "balls" person but I am completely obsessed with Smartballs!!! When my package arrived I was like "yay something I can play with all day long and no one will even know it!" So after taking my lovely balls out of their case and giving them a couple of jingles, just for shits and giggles, I washed them off and used the lube that was provided to make it easier to insert. Now I have to tell you I have a "short" vagina and had a hard time trying to cram these guys in, but I eventually did! After that was done I started to walk and instantly stopped so I could giggle. The feeling was intense and so unique that I just couldn't help myself. I swear I was giggling like crazy. As the day continued I was feeling better and better as I cleaned my house with the Smartballs going to town. My house has never been so clean!!! Once that was all done I decided to take them on a test drive, literally! I jumped in my car and road over bump after bump out in the country and in the city and they were great! So I guess I can honestly say you can wear these any where. I did not experience an orgasm on my first day of using it, although the look of the Smartballs told differently. They give a GREAT workout and I've noticed a change in the bed since I use them everyday. I recommend this to everyone whether you need to do kegal exercises or not these are a must have!!!! http://shop.tootimid.com/fun-factory-smartballs.aspx
