Absolutely! However, you can have sex only when you’re not wearing the device. Trying to have sex or jerk off with your penis extender is definitely not recommended. If you wear the penis stretcher for the recommended number of hours, you can take it off and have a little fun with your partner without any worries. And, as an added reward, having sex or wanking off after you remove the penis stretcher will improve your blood flow and ultimately speed up the expansion process. So jerk away!
