If you want to try something more disposable before opting for something like the Tenga Fliphole or the Fleshlight, i'd definitely recommend the Tenga onacups. Lovehoney stock loads, and my OH loves them.
You can prolong the use of the Tenga Onacup with using a condom and rising it afterwards. Then use lubricant with each use. It will eventually need to be disposed of but you will get more than one use out of it.
