Hi, never had Sex. If I masturbate, I cum after idk something around 5 to 10 minutes. After that my Penis gets a little bit softer but stays erected and I can continue longer. How is that in Sex with a condom? Should I change the condom after I came the first time? Immediately or just before I cum a second time? How to change it? How to do it so my Penis stays hard, because if I dont get stimulation after I came my penis gets softer. Any other tips? Is there a good SexEd video channel, preferrable on a porn video plattform like pornhub?
