Performing Oral Sex on a Man ("blowjob", "head")

In addition to good oral hygeine, proper use of a non-lubricated or flavored condom on a man can significantly decrease risk of HIV transmission. If a condom is not available or an option, not accepting semen into the mouth or spitting rather than swallowing will reduce the risk. You can also use the "harmonica method" by focusing on the shaft of the penis while avoiding the head.
