After I administer MUSE (alprostadil), can we immediately lie down and begin sexual activity?
You can begin sexual activity. However, having the man lie down, especially on his back right after administration, is not recommended. This will reduce blood flow to the penis and may reduce the erection. It is important to sit, stand or walk about for 10 minutes. Many couples have used this time for foreplay. After this initial period, you can assume different positions leading to sexual intercourse. Some couples have noticed that the erection is better maintained in positions that favor blood flow into the penis during intercourse.
