It combines two of our most popular products in a lighter, more discreet and portable version. Like its full-size predecessor, GO Stamina was designed to replicate the most intense sensations of intercourse, which can help you increase sexual stamina, improve performance, and increase and intensify orgasms. GO Stamina gives you the same wild ride but in a more compact size, so you can train wherever you go.
