The app-connected F2S™ stamina trainer and stroker is here to revolutionize men's pleasure with its open-ended liquid silicone design for unrestricted enjoyment. We feel that sexual performance is like any other skill; harnessing its full potential involves many stages of progress before reaching mastery. That is why, when connected to the LELO™ app, F2S™ transforms into the ultimate endurance trainer with two specially developed exercise routines. The stamina trainer helps you build endurance and experience more powerful orgasms. Guided Kegel exercises for men will help you ensure a more satisfying sexual performance.
HIGHLIGHTS
1 - APP-CONNECTED STAMINA TRAINER
Use the stamina trainer or the guided Kegel exercises for men to enhance your sexual performance. You can also unlock six additional vibration modes exclusively using the LELO™ app. Click here for more details.
2 - AI INTERACTIVE MODE
A performance feedback sensor inside F2S™ emits real-time encrypted information based on the device's movement. Then, the AI INTERACTIVE mode in the LELO™ app syncs the intensity and motion perfectly with the device's movement.
3 - LIQUID SILICONE
This real-feel material is the embodiment of softness, elasticity, and durability. It doesn't just conform to your needs; it elevates your experience.
4 - FIFTEEN POWERFUL PLEASURE SETTINGS
The product alone has eight settings; with the LELO™ app, you can unlock seven extra modes.
5 - AUTO-ADJUSTED LIQUID SILICONE RIBS
The newly introduced silicone ribs allow for airflow, eliminating the creation of air pockets while providing an added point of stimulation.

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.
