Be sure to use lubricant without regret for any penetration – with a finger, a toy or a penis. There is no natural lubrication in the rectum, unlike in the vagina, and if you don’t give a damn about discomfort, then those very internal injuries are definitely not needed by anyone. Apply the lubricant to both the entire surface and the inside of the penis. A silicone-based lubricant is generally recommended because it dries more slowly, but a recent blind study found that many people like water-based products even better. Check which one is right for you and remember that water-based lubricants are easier to rinse off your body and wash off your sheets. Vaseline, oil and greasy creams are not suitable – they destroy the latex of condoms.
