How F2S™ endurance trainer works

We at LELO strongly believe that sexual performance is like any other skill - it is not given, and it should not be taken for granted. To help you master that skill, you can choose between carefully developed stamina training or a guided Kegel exercise routine for men inside the LELO™ app. To optimize your success, start with the Kegel exercises, then proceed to the stamina training. Kegel exercises for men involve contracting and relaxing the pelvic floor muscles, which control bladder function and support erectile strength. Strengthening these muscles can lead to better endurance, stronger erections, and improved control over ejaculation for more satisfying sexual performance. Whichever option you choose, you can count on increasing your orgasmic prowess in no time.
