You want 3 somes, 4 somes or more, do it. But never, never at your place. Always in their place. And when you go, only take the exact amount agreed and nothing else in your pockets. And of course, use protection, as non protected oral also has a certain risk to get hiv, syphills and other disease. Not to mention the other skin diseases like Scabies that are a nightmare and can be caught just by skin contact.
