Hi there! So me and my girlfriend want to dry hump naked, however we can't purchase condoms since they require ID's and you need to be 18 or above to buy them here in our country. Is it okay if I tape the tip of my penis? We are sure that we will not go any further. We have already dry humped a few times before, and it didn't lead us to into sex since we know our limits. We usually just dry hump for about 10-15 minutes and I never ejaculate. I also urinate before doing such act to kill any sperm in my pre-***. Now, we just want to be extra safe.
