Have a big one and think our regular sleeves are a bit snug? Or do you want to lessen the stimulation level to train yourself to last longer? You’re in luck! Our Stamina Training Series sleeves are 50% wider to accommodate larger penises and offer less stimulation due to their wider internal dimensions. The internal patterns match those of our dependable standard series of sleeves, offering realistic and pleasurable stimulation to those who desire a looser fit. So break out the Fap Lube, pick up a stamina training sleeve, and get ready for an extra long fun session!
