My husband started with the Tenga Eggs — each of which he was able to use multiple times — then gave the Tenga Deep Throat Cup US a try. He loved the feel of the cup, but a) the US was a very tight fit because it's not as stretchy as the eggs, and b) he could not clean the cup to get a second use out of it. They're a little expensive for single-use, so I bought him a Fleshlight during a Crazy Thursday sale instead: he
it. (He would have tried a Flip Hole, but they were out-of-stock at the time).
Let your boyfriend try the cup once. If he doesn't like it, you probably shouldn't waste your money on a Fleshlight or Tenga Flip. If he likes it, make the investment in a mulitple-use toy.
